DepthBufferClear()

float

value

Definition at line 82 of file RenderTarget.cpp.

DepthBufferMode()

void iv::RenderTarget::DepthBufferMode	(	GLenum	test_condition,
		bool	write_enabled
	)

test_condition GL_ALWAYS, GL_LESS, GL_GREATER, ... (is forwarded to glDepthFunc).

bind_texture()

void iv::RenderTarget::bind_texture	(	int	texture_unit,
		GLuint	texture_id
	)

Definition at line 57 of file RenderTarget.cpp.

bind_shader()

void iv::RenderTarget::bind_shader

(

GLuint

program_id

)

Definition at line 75 of file RenderTarget.cpp.

frame_setup()

void iv::RenderTarget::frame_setup ( )

protected

Called before each render, when gl context is already available. This will reset the state of opengl context to default. It will also reset state of RenderTarget.

Definition at line 30 of file RenderTarget.cpp.

frame_close()

void iv::RenderTarget::frame_close ( )

protected

Called after each render. This clears bound textures and such. Might get used for safety - so that bound gl texture from render does not get modified by invalid code outside of render.

Definition at line 43 of file RenderTarget.cpp.

set_geometry()

void iv::RenderTarget::set_geometry ( Geometry  geometry )

protected

Geometry values are used during rendering by renderer components.

Definition at line 47 of file RenderTarget.cpp.

Member Data Documentation

MaxTexturingUnits

const constexpr int iv::RenderTarget::MaxTexturingUnits = 2

staticconstexpr

This is used so that I can handle more than one texturing unit. To realy reliably use more than 2 (guaranteed for GLES), I should read that value from GL, make this dynamic (dynamically allocated arrays) and do some verification (error message on fail).
