Constructor & Destructor Documentation

omega::GpuContext::GpuContext ( GLEWContext *  ctx = NULL)

Initializes a GPU context.

If the passed GLEW context is null, a glew context will be created internally and GLEW will be initialized by this contstructor.

Remarks
This method needs to be called from within a valid OpenGL context.

Member Function Documentation

GpuProgram* omega::GpuContext::createProgram ( )
RenderTarget* omega::GpuContext::createRenderTarget ( uint  type)
Texture* omega::GpuContext::createTexture ( )

Resource management.

VertexArray* omega::GpuContext::createVertexArray ( )
VertexBuffer* omega::GpuContext::createVertexBuffer ( )
void omega::GpuContext::garbageCollect ( )

Destroys all GPU resources that are not referenced anywhere.

Remarks
This method is typically called by the Renderer at the end of each frame but can be invoked anywhere from the rendering thread associated with this context.
