Quartzcode vertex mode12/29/2023 If enabled, calls to glEvalCoord1, glEvalMesh1, and glEvalPoint1 generate s texture coordinates. If enabled, calls to glEvalCoord1, glEvalMesh1, and glEvalPoint1 generate normals. If enabled, calls to glEvalCoord1, glEvalMesh1, and glEvalPoint1 generate color indexes. If enabled, calls to glEvalCoord1, glEvalMesh1, and glEvalPoint1 generate RGBA values. If enabled, apply the currently selected logical operation to the incoming and color-buffer indexes. If enabled, use the current line stipple pattern when drawing lines. If enabled, draw lines with correct filtering. See glMaterial, glLightModel, and glLight. ![]() If disabled, associate the current color or index with each vertex. If enabled, use the current lighting parameters to compute the vertex color or index. If enabled, include light i in the evaluation of the lighting equation. If enabled, apply the current logical operation to the incoming index and color buffer indices. If enabled, blend a fog color into the post-texturing color. If enabled, dither color components or indexes before they are written to the color buffer. If enabled, do depth comparisons and update the depth buffer. ![]() If enabled, cull polygons based on their winding in window coordinates. If enabled, have one or more material parameters track the current color. If enabled, apply the current logical operation to the incoming RGBA color and color buffer values. If enabled, clip geometry against user-defined clipping plane i. If enabled, blend the incoming RGBA color values with the values in the color buffers. If enabled, compute surface normal vectors analytically when either GL_MAP2_VERTEX_3 or GL_MAP2_VERTEX_4 has generated vertices. ![]() Use glIsEnabled or glGet to determine the current setting of any capability.īoth glEnable and glDisable take a single argument, cap, which can assume one of the following values: Value The glEnable and glDisable functions enable and disable various OpenGL graphics capabilities. The function was called between a call to glBegin and the corresponding call to glEnd. NameĬap was not one of the values listed in the preceding Remarks section. The following error codes can be retrieved by the glGetError function. Syntax void WINAPI glDisable(Ī symbolic constant indicating an OpenGL capability.įor discussion of the values cap can take, see the following Remarks section. The glEnable and glDisable functions enable or disable OpenGL capabilities.
