Weblayout (triangles) in; layout (triangle_strip, max_vertices=3) out; layout (lines) in; layout (line_strip, max_vertices=2) out; The shader will compile and run, but will only render lines (or whatever the last primitive defined is). So how do I define a single geometry shader that will handle multiple types of primitives? WebOpenGL supports several basic primitive types, including points, lines, quadrilaterals, and geneneral polygons. All of these primitives are specified using a sequence 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].

For a triangle strip with adjacency, the leading vertices are 0, 2, 4, 6, and so on. For a line strip with adjacency, the leading vertices are 1, 2, 3, and so on. An adjacent primitive, on the other hand, has no leading vertex.

WebOpenCL makes no requirement about the alignment of OpenCL application defined data types outside of buffers and images, except that the underlying vector primitives (e.g. __cl_float4) where defined shall be directly accessible as such using appropriate named fields in the cl_type union.
