10/3/2023 0 Comments Triangular tessellation creatorThe subdivision, flatness test, and final vertex attribute calculations are done using fragment programs (pixel shaders). This chapter takes a repeated subdivision approach to tessellation, implemented by rendering into 2D textures. The second part of this chapter describes how to add displacement-mapping support for rendering highly detailed models that can be animated in real time. The first part of this chapter explains how to tessellate subdivision surfaces to polygons for rendering high-quality curved surfaces without visible polygon artifacts. We use the GPU to do the tessellation calculations, which saves graphics bus bandwidth and is many times faster than using the CPU. In this chapter we describe how to perform view-dependent, adaptive tessellation of Catmull-Clark subdivision surfaces with optional displacement mapping.

Shodor's academic program efficiently guides participants from excitement to experience to expertise through computational explorations, research opportunities, and service. Resources and materials offered to these instructors are available free of charge from Shodor's website and are largely developed by Shodor student interns. Additionally, the National Computational Science Institute (NCSI) provides nation-wide workshops portraying resources and instructional ideas to middle school, high school, and undergraduate instructors for use in the classroom. Student development of numerical models and simulations integrated with core curriculum provides an opportunity to gain practical experience in computational science. On a mission to transform learning through computational thinking, Shodor is dedicated to the reform and improvement of mathematics and science education through student enrichment, faculty enhancement, and interactive curriculum development at all levels. Corners of the polygons may be dragged, and corresponding edges of the polygons may be dragged. Tessellate!: Create a tessellation by deforming a triangle, rectangle or hexagon to form a polygon that tiles the plane.
