Material may continue to be added and/or edited throughout the semester. I always try to have additions and edits posted before the class in which they are first covered. If the holes and/or concavities are much more complex (e.g., the wall image in the middle on the right), it becomes unreasonable to create the model geometry 'by hand'. Material may continue to be added and/or edited throughout the semester. I always try to have additions and edits posted before the class in which they are first covered. A quick glimpse at the structure of the approach we will take in 'defineModel' and 'render' (CPU) and in the vertex shader (GPU) Example: Use the strategy introduced at the bottom of 'Deriving Affine Transformations' to derive the view orientation affine transformation that maps model coordinates to eye coordinates. We will see more examples of this technique when deriving additional affine transformations such as mirror, scale, and rotation. This routine allows the OpenGL programmer to specify several important aspects related to how the built-in GLSL function Hybrid approaches possible. For example, if large, easily identifiable and separable portions of the scene are opaque, draw them first with ' Simple concave shapes and/or shapes with simple holes are oftentimes easily constructed using the various triangle primitive types we have seen. (See the two sample shapes above and on the right.) If the holes and/or concavities are much more complex (e.g., the wall image in the middle on the right), it becomes unreasonable to create the model geometry 'by hand'. The geometry you define to the tessellator must be planar. Your results are undefined otherwise. However, you can use the facility on curved surfaces that have a parametric representation: Source.
