Class PainterGPUConformance

java.lang.Object

org.jzy3d.junit.PainterGPUConformance

public class PainterGPUConformance
extends Object

Verify that a painter supports the GPU resources API of IPainter (buffer objects, shaders, textures, framebuffers, queries) by drawing in its current GL context and reading back pixels. The painter must have a current GL context with a framebuffer of at least WIDTH x HEIGHT pixels. Each check prepares the context with prepare().
