VROverlayError SetOverlayTexture( VROverlayHandle_t ulOverlayHandle, GraphicsAPIConvention eTextureType, void* pTexture )

Texture to draw for the overlay.

• VROverlayHandle_t ulOverlayHandle - Handle of the overlay to set the texture for
• GraphicsAPIConvention eTextureType - Either API_DirectX or API_OpenGL depending on what the texture pointer refers to
• void* pTexture - Pointer to the texture in question. See description

• API_DirectX - pTexture must be a pointer to one of:
  • ID3D10Texture*
  • ID3D11Texture*
• API_OpenGL - pTexture must the GLuint of the texture
  • Supported formats on Windows:
    • Linear:
      • GL_RGBA16
      • GL_RGBA16F
      • GL_RGB16F
    • sRGB:
      • GL_RGBA8
