WebIf you want slightly less index data, you can use primitive restart indices.This allows you to designate an index to mean "restart the primitive". This allows you to use a GL_TRIANGLE_STRIP primitive and break the primitive up into pieces while still only having a single draw call.

Web28 de fev. de 2008 · There are ten geometric primitives in OpenGL, from a point to a polygon, and all are represented by vertices. This program will give you the flexibility to add and remove vertices in a certain order, and shows you how the choice of the primitive determines how the vertices are to be combined. It can be used in the following ways: WebAs opposed to other OpenGL primitive types, patches have a user-defined number of vertices. Function glPatchParameteri is used to set this value, which remains constant in draw calls, as follows: glPatchParameteri( GL_PATCH_VERTICES, verticesPerPatch ); where verticesPerPatch must be an integer in [1, GL_MAX_PATCH_VERTICES].
