![]() ![]() Note that these arrays are a bit more flexible than C arrays, but overall work the same way. All of these arrays must have the same number of elements. This set of attributes defines what values the vertex stream must provide to properly render with this shader.įor each attribute in the shader, you must provide an array of data for that attribute. The VS's user-defined input variables defines the list of expected Vertex Attributes for that shader, where each attribute is mapped to each user-defined input variable. In order to render at all, you must be using a shader program or program pipeline which includes a Vertex Shader. Submitting vertex data for rendering requires creating a stream of vertices, and then telling OpenGL how to interpret that stream. ![]()
