Detailed Description

Multiple textures may be attached and share a single depth and stencil buffer. Usage sample:

    fb = fxMgr->CreateFramebuffer(512, 512, 24, 0);
    fb->BeginCapture();
    fb->AttachTexture(0, GL_TEXTURE_2D, texture, 0, 0);
    fb->IsValid();
    ... render to texture ...
    fb->EndCapture();
    glBindTexture(GL_TEXTURE_2D, texture);
    ... render using rendered texture...

virtual bool GLFX::IFramebuffer::BeginCapture

(

)

[pure virtual]

Begins rendering to this framebuffer.

Returns:

true if successful

virtual void GLFX::IFramebuffer::EndCapture

(

)

[pure virtual]

Ends rendering to the framebuffer.

virtual bool GLFX::IFramebuffer::AttachTexture	(	long	attachment,
		GLenum	textarget,
		GLuint	texture,
		GLint	level,
		GLint	zoffset
	)			[pure virtual]

Attaches OpenGL texture to the framebuffer.

Parameters:

	attachment	attachment point number
	textarget	texture target, one of GL_TEXTURE_1D, GL_TEXTURE_2D, GL_TEXTURE_3D GL_TEXTURE_CUBE_MAP_POSITIVE_X, GL_TEXTURE_CUBE_MAP_NEGATIVE_X, GL_TEXTURE_CUBE_MAP_POSITIVE_Y, GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, GL_TEXTURE_CUBE_MAP_POSITIVE_Z or GL_TEXTURE_CUBE_MAP_NEGATIVE_Z
	texture	OpenGL texture id
	level	mipmap level
	zoffset	z-offset if 3d texture

Returns:

true if successful

virtual bool GLFX::IFramebuffer::IsValid

(

)

[pure virtual]

Tests if framebuffer is complete and can be rendered to.

Returns:

true if framebuffer is complete

virtual void GLFX::IFramebuffer::SetDrawBuffer

(

long

attachment

)

[pure virtual]

Sets a attached texture as current draw buffer.

Parameters:

attachment

attachment number
