◆ BlitToDrawBuffer()
| void Wizt::MultiviewOVR::BlitToDrawBuffer | ( | VRenderContext & | Context, |
| const ViewportGeometry & | VP, | ||
| unsigned | NumberOfEyes, | ||
| unsigned | ActiveEye, | ||
| const RefPtr< Framebuffer > & | Target | ||
| ) |
Ensures depth writes occur during fullscreen blit passes.
When performing a fullscreen blit that writes a custom depth value via gl_FragDepth, the depth test must remain enabled. Disabling the depth test (glDisable(GL_DEPTH_TEST)) can cause some drivers to bypass the entire depth pipeline, which prevents gl_FragDepth from updating the default framebuffer's depth buffer even if depthMask is enabled. To guarantee correct depth writes, enable depth testing and use GL_ALWAYS as the depth function:
glEnable(GL_DEPTH_TEST); glDepthFunc(GL_ALWAYS);
This keeps the depth pipeline active while ensuring all fragments pass and the shader-provided depth value is written as intended.

◆ UserBlitAnemoneCreator
| WeakPtr<AnemoneBasicCreator> Wizt::MultiviewOVR::UserBlitAnemoneCreator |
Overriding the way how the framebuffer texture is blit to the screen.
The AnemoneCreator must be stored at some RenderAble object such that this WeakPtr recognizes when this object has been removed.
