 B. "INTRODUCTION TO COMPUTATIONAL GEOMETRY" (Half-day) - Mon 26 June (am)
     Professor Godfried Toussaint (McGill University, Canada)

 This course is an introduction to computational geometry at the
 undergraduate level.  Basic knowledge of data structures and the design
 and analysis of algorithms is assumed.

 The course consists of ten units or chapters.  Part 1 places
 computational geometry in perspective with respect to classical
 geometry, introduces convex sets and metric as well as combinatorial
 aspects of geometry, and briefly touches upon aspects of the design and
 analysis of algorithms including worst-case and expected complexity,
 lower bounds, data structures and bucketing methods. Part 2 considers
 the diameter of a set.  Algorithms are given for sets of points and
 convex polygons.  The relationship between complexity convexity, and
 unimodality is explored.  Part 3 considers convex hulls in two
 dimensions.  For sets of points we compare Jarvis' algorithm with that
 of Graham.  We also show how to obtain algorithms with fast expected
 running time by using the "throw-away" principle.  This material
 naturally leads to triangulations, the topic of Part 4.  We present
 several algorithms for triangulating simple polygons, algorithms for
 triangulating sets of points to obtain triangulations with particular
 geometric properties, as well as the Delaunay triangulation.  In Part 5
 we discuss algorithms for intersecting convex polygons and half-planes
 efficiently.  Part 6 introduces nearest and furthest point Voronoi
 diagrams including algorithms and applications to other geometric
 problems including minimal spanning trees, relative neighbourhood
 graphs, closest-point problems, the diameter, and furthest-point
 problems.  Part 7 presents algorithms for computing maximum and minimum
 distances between sets.  Part 8 treats visibility problems.  Art gallery
 theorems are illustrated with the theorem of Chvatal and the algorithm
 of Avis and Toussaint.  Several problems concerned with visibility from
 a point (strong visibility) are covered including the recognition of
 star-shaped polygons and the algorithm of ElGindy and Avis for computing
 the visibility region from a point.  Finally we consider weak visibility
 (visibility from a region such as a line).  In particular we treat the
 recognition problem as well as the problem of constructing the weak-
 visibility region from a line segment.  Part 9 is concerned with
 computing geodesic properties of polygons.  In particular we present
 algorithms for computing the geodesic path between two points in a
 polygon, the geodesic center of a polygon, and the geodesic convex hull.
 Finally, the topic of movable separability of sets is treated in Part 10.
 First we discuss the sofa problem. Then we show how to determine if two
 simple n-gons can be separated by a single translation in time O(T(n))
 where the best value of T(n) thus far is O(n log log n).  We conclude
 by discussing the problem of separating sets of polygons by simultaneous
 translations.

 C. "STATE OF THE ART IN COMPUTER ANIMATION" (Half-day) - Mon 26 June (am)
     Professor Brian Wyvill (University of Calgary, Canada)

 In this seminar the three basic elements of computer animation are
 reviewed, i.e. Modelling, Motion control and Rendering.  An overview of
 modelling techniques along with current trends in ray tracing will be
 surveyed.  Emphasis is placed on techniques for motion control and
 modelling methods suited to shape distortion such as iso-surfaces.
 Spline based motion curves, track animation and inbetweening will be
 shown with examples.   A further example in dynamics will be covered
 along with an overview of current trends in face animation.   This
 includes both parametric and muscle models and recent work in skin
 modelling techniques and lip synch. of synthesised speech.  Mention will
 be mades of both constraint and goal based animation.  Animation systems
 will be covered from general purpose languages, interactive and command
 languages through to an analysis of the design and implementation of
 an experimental object-oriented animation system.

 D. "COMPUTER GRAPHICS IN EDUCATION" (Half-day) - Mon 26 June (am)
     Mr Mike Gigante (Royal Melbourne Institute of Technology, Australia)

 This tutorial will focus on two issues:

         --   How Computer Graphics can be taught effectively.
         --   How high performance Computer Graphics can increase the
                effectiveness of education in other areas.

 Teaching Computer Graphics
 The speaker will present a series of tools that he uses to teach 3D
 interactive computer graphics to programming-naive Mechanical
 Engineering students. Although these students have little programming
 background, they have developed some quite sophisticated 3D
 applications. The speakers agues that these tools and their usage have
 added value to the learning process.

 The extension of this work has led to the development of similar tools
 in Boxer, the educational computing environment developed by Prof
 Andrea DiSessa at the University of California at Berkeley. Boxer was
 originally developed at MIT by the same team that developed Logo. The
 Boxer graphics environment developed by the speaker will be discussed.

 Graphics to Improve Understanding
 Although this is not a new concept, the speaker believes that
 insufficient attention has been paid to the rewards of this area. He
 will present a series of programs that are used in the undergraduate
 program at RMIT, explain how they are used, and the techniques that
 previously were used.

 The greatest benefit of this work is the improvement of the student's
 qualitative understanding. At a time where computers are being used
 for most numerical calculations, it is more important than ever that
 the user of these numerical techniques has a solid understanding of
 the basic behaviour of these systems. Some examples include:

                     - solid mechanics
                     - potential flow/electrostatics
                     - structural dynamics
                     - kinematic/dynamic systems

 E. "NEW HORIZONS FOR 4D MODEL APPLICATIONS" (Half-day) - Mon 26 June (pm)
     Professor Tosiyasu L. Kunii (University of Tokyo, Japan)

 This tutorial is for everyone wishing to take advantage of recent
 advances in 4D graphics technology.  Exploitation of 2D and 3D graphics
 has contributed to our problem-solving capabilities.  This is now
 increased and enhanced by the modelling facilities available in 4D.
 Applications of 4D models are shown in association with explanation of
 how to derive 4D models from actual cases.  The application cases
 shown includes: An Inner Trip Through a Human Ear, Walking Through a
 Room, a Gemstone Fire Waltz, a Tibetan Mandala Drawing, Looking into
 Parallel Processor Performance, Botanical Tree Growth, the Art of Skiing
 and the World of Oriental Martial Arts.

 F. "THE MECHANICAL UNIVERSE" (One-day) - Mon 26 June(pm) & Tues 27 June(am)
     Dr James F. Blinn (California Institute of Technology, USA)

 The Mechanical Universe is a 52 episode telecourse covering basic
 freshman physics.  The series makes extensive use of computer
 animation to illustrate various mathematical and physical
 processes.  Many concepts translate easily into the animation
 realm, notably the illustration of the dynamic behavior of
 systems, forming a sort of "animated textbook diagram".  But the
 use of color video yields two degrees of freedom beyond that
 available in traditional textbook diagrams: color and motion.  The
 effective use of these extra tools required the design of a wide
 range of new visual metaphors for such concepts as dimensional
 analysis, algebraic manipulations, and limits.  This Tutorial will
 discuss some of these metaphors and the thoughts that went into
 their design, will show some examples of the animations and will
 discuss a new animation project for mathematics education.

 BOOKING ARRANGEMENTS

 Advance Registration is required, on the Booking Form at the end of

 AUDIENCE:
 This Conference and Exhibition is important for all those concerned with
 research, development, or use of computer graphics and associated
 techniques.  Visualisation in science and engineering is becoming
 an increasingly important tool for research.  The fields of graphics and
 image processing are moving closer together through the important
 developments on the hardware front, and each will benefit greatly
 from this mutual association.  This Conference will bring together
 many of the leading key researchers in these fields.  This symbiosis
 will be important for all those having a serious interest in
 evaluating current research work and profiling future developments and
 applications.

 DELEGATE APPLICATIONS
 Applications are now invited on the Booking Form attached (or photopcopy
 thereof).  Advance registration is required in order to reserve a place.
 Early application is strongly advised in order to guarantee a place.
 This is a once-only opportunity in Europe to hear leading-edge topics
 in this fast-moving field presented by international researchers.

 Delegates may register for the Conference and/or the Pre-Conference
 Tutorial(s) according to whatever they require.
 Please note that payment with booking is encouraged, or you may
 request an Invoice to be issued for the appropriate amount.  Invoices
 must be paid by the due date and places will only be confirmed on receipt
 of payment. Cheques must be made payable to 'UNIVERSITY OF LEEDS'.
 Only cheques or banker's drafts in sterling will be accepted.
 Delegates from other countries who wish to submit payment can only do
 so by purchasing a sterling bank draft from a bank in their own country
 (this will be made out in sterling on a UK bank) and forward this
 with their Booking Form.  Eurocheques will NOT be accepted due to high
 conversion charges on receipt.  Delegates are reminded of the Early Bird
 Reduced Registration Rate applicable to all applications received by the
 Secretariat on or before 24 April 1989.  After this date the full rate
 will apply.

 COSTS
 The Registration Fee covers admission to all the Technical Sessions and
 the Exhibition, a copy of the printed Proceedings volume to be available
 at Registration, and also enables us to cover all the administrative
 costs and the hire of the venue and facilities.  Note that members of
 the co-sponsoring organisations: Computer Graphics Society(CGS) and
 British Computer Society(BCS) are entitled to the reduced Registration
 Rate, but MUST specify their membership number in the space provided
 on the Booking Form.  Please note that Registration does not include
 accommodation and meals and this is covered by a separate Accommodation
 Fee.  All fees are specified in pounds sterling ($).

 VAT (15%) has to be added to the Accommodation Fee giving
 a total of $126.50 for the Conference and $40.25 for each Tutorial night.

 Multiple discounts are not possible (e.g. a full-time postgraduate
 student who is also a member of the BCS can only claim one reduction).
 The Conference is fully residential and accommodation is provided at a
 most economical rate in the University for all those who require it.
 The University Accommodation fee includes all meals, teas, coffees, etc
 from lunch on 27 June to tea on 30 June, and also the main Conference
 Reception and Banquet.
 Those who require more comfort or more facilities can stay in a high
 standard Hotel (The Parkway, Lawnswood, Tel 0532 672551) which is close
 by the Conference venue (Bodington Hall, Lawnswood) and take meals at
 Bodington Hall. In this case, delegates should  submit the Registration
 Fee only. (Full details of the Hotel will be supplied on request. Bed
 and  Breakfast at the Hotel will cost around $50 per night (inclusive of
 VAT).  Day attendance will be $20 per day - inclusive of VAT.  Thus the
 Hotel plus Conference meals totals $210 for the period of the Conference
 (3 days)).
 The Conference Reception is sponsored by Silicon Graphics, and the
 University of Leeds, and will be hosted by the Vice-Chancellor
 of the University, Sir Edward Parkes.

 CANCELLATION AND SUBSTITUTION
 Substitutions can be made at any time.  A registered delegate who
 becomes unable to attend may nominate a substitute for the Conference.
 The amount of fees then due (if any) is according to the eligibility
 of the substitute who will pay for any difference owing (e.g. if they
 are not a member of any of the sponsoring societies).  Cancellations
 can only be accepted if received in writing by the Secretariat not
 later than 30 days prior to the Conference.  A 20% administration
 and handling charge will be deducted from any fees refunded.  Less
 than 30 days before the Conference all fees are non-returnable unless
 a substitute can be found from the Waiting List.  The Committee
 reserve the right to make programme changes without notice, if
 required, and do not accept responsibility for the speakers' travel
 arrangements.
