static void set(SoState *state, SoDepthBuffer *depthBuffer, const SbBool test, const SbBool write, const DepthWriteFunction function, const SbVec2f range)
Sets the depth buffer parameters.
DepthWriteFunction
Depth function mode as defined by OpenGL.
@ NOTEQUAL
Passes if the incoming depth value is not equal to the stored depth value.
@ EQUAL
Passes if the incoming depth value is equal to the stored depth value.
@ LESS
Passes if the incoming depth value is less than the stored depth value.
@ GREATER
Passes if the incoming depth value is greater than the stored depth value.
@ GEQUAL
Passes if the incoming depth value is greater than or equal to the stored depth value.
@ LEQUAL
Passes if the incoming depth value is less than or equal to the stored depth value.
virtual void print(FILE *fp) const
Prints element (for debugging).
virtual void push(SoState *state)
Override push() method to keep GL up to date.
static void get(SoState *state, SbBool &test, SbBool &write, DepthWriteFunction &function, SbVec2f &range)
Returns current depth buffer parameters.
static void set(SoState *state, const SbBool test, const SbBool write, const DepthWriteFunction function, const SbVec2f range)
Sets the depth buffer parameters.
virtual void pop(SoState *state, const SoElement *prevTopElement)
Override pop() method to keep GL up to date.
