function
Rendering::OcclusionQuery::enableTestMode

public

static

void enableTestMode(	RenderingContext &	renderingContext )

Pushes the current gl state, disables lighting, color writes and depth writes.

Note: After calling enableTestMode() you always have to call disableTestMode(context.getRenderingContext()) eventually (as internally glPushAttrib() / popAttrib() is used).
