GlProgram

Base class for a program that accepts a vertex and a fragment shader in the constructor. The program will be created automatically and released when release is called.

Subclasses are required to do two things - typically, during the onPreDraw callback: 1 Inspect the GlDrawable properties:

• GlDrawable.vertexArray

• GlDrawable.coordsPerVertex

• GlDrawable.vertexStride These should be passed to the vertex shader. 2 Pass the MVP matrix to the vertex shader as well.

The vertex shader should then use the two to compute the gl_Position.
