Detailed Description

OpenGL GraphRenderer.

All GraphRegion rendering operations utilize a GraphRenderer.

The GraphRenderer owns its RenderState, a composition.

The GraphRenderer manages and owns all used ShaderProgram instances, a composition.

At its destruction, all ShaderPrograms and its RenderState will be destroyed and released.

Member Data Documentation

◆ defaultBlendEnable

GraphRenderer::GLCallback GraphRenderer::defaultBlendEnable

static

Initial value:

= [](GL&, GraphRenderer& renderer) {
    if( renderer.renderState().hintBitsSet(RenderState::BITHINT_GLOBAL_DEPTH_TEST_ENABLED) ) {
        ::glDepthMask(false);
        
        
    }
    ::glEnable(GL_BLEND);
    ::glBlendEquation(GL_FUNC_ADD); 
    renderer.renderState().setHintBits(RenderState::BITHINT_BLENDING_ENABLED);
}

Default GL#GL_BLEND enable GLCallback, turning-off depth writing via GL#glDepthMask(bool) if RenderState#BITHINT_GLOBAL_DEPTH_TEST_ENABLED is set and turning-on the GL#GL_BLEND state.

Implementation also sets RenderState's blending bit-hint, which will cause GLRegion's draw-method to set the proper blend-function and the clear-color to transparent-black in case of multipass FBO rendering.

See also: #create(GLCallback, GLCallback); #enable(GL2ES2, bool)

Definition at line 81 of file GraphRenderer.hpp.

◆ defaultBlendDisable

GraphRenderer::GLCallback GraphRenderer::defaultBlendDisable

static

Initial value:

= [](GL&, GraphRenderer& renderer) {
    renderer.renderState().clearHintBits(RenderState::BITHINT_BLENDING_ENABLED);
    ::glDisable(GL_BLEND);
    if( renderer.renderState().hintBitsSet(RenderState::BITHINT_GLOBAL_DEPTH_TEST_ENABLED) ) {
        
        
        ::glDepthMask(true);
    }
}

Default GL#GL_BLEND disable GLCallback, simply turning-off the GL#GL_BLEND state and turning-on depth writing via GL#glDepthMask(bool) if RenderState#BITHINT_GLOBAL_DEPTH_TEST_ENABLED is set.

Implementation also clears RenderState's blending bit-hint.
