Detailed Description

Class for off-screen GL rendering.

This class provides platform-independent names for GL functions related to framebuffers.

The user MUST call initialize() before using any static members of this class.

Member Function Documentation

◆ hasFrameBuffers()

static bool hasFrameBuffers ( )

static

Check if frame buffers are available.

This function will always return false, if initialize() has not been called.

Returns: true if frame buffers are available, false otherwise.

◆ initialize()

static bool initialize ( )

static

Try to initialize frame buffers.

Returns: true if initialization succeeded.

◆ isFrameBuffersInitialized()

static bool isFrameBuffersInitialized ( )

static

Check if frame buffers has been initialized.

Returns: true if initialized, false otherwise.

◆ test()

static void test ( rw::core::LogWriter & log )

static

Print some information about the frame buffers to the log.

Parameters

log	[in/out] the log to write to.

◆ testFrameBufferCompleteness()

static bool testFrameBufferCompleteness ( )

static

Check for framebuffer completeness. Only use the framebuffer if this succeeds.

Returns: true if framebuffer is complete.
