glutSetColor(3GLUT)						       GLUT						       glutSetColor(3GLUT)

glutSetColor - sets the color of a colormap entry in the layer of use for the current window. SYNTAX
#include <GLUT/glut.h> void glutSetColor(int cell, GLfloat red, GLfloat green, GLfloat blue); ARGUMENTS
cell Color cell index (starting at zero). red Red intensity (clamped between 0.0 and 1.0 inclusive). green Green intensity (clamped between 0.0 and 1.0 inclusive). blue Blue intensity (clamped between 0.0 and 1.0 inclusive). DESCRIPTION
Sets the cell color index colormap entry of the current window's logical colormap for the layer in use with the color specified by red, green, and blue. The layer in use of the current window should be a color index window. cell should be zero or greater and less than the total number of colormap entries for the window. If the layer in use's colormap was copied by reference, a glutSetColor call will force the duplication of the colormap. Do not attempt to set the color of an overlay's transparent index. SEE ALSO

glutLayerGet(3GLUT)						       GLUT						       glutLayerGet(3GLUT)

glutLayerGet - retrieves GLUT state pertaining to the layers of the current window. SYNTAX
#include <GLUT/glut.h> int glutLayerGet(GLenum info); ARGUMENTS
info Name of device information to retrieve. GLUT_OVERLAY_POSSIBLE Whether an overlay could be established for the current window given the current initial display mode. If false, glutEstablishOver- lay will fail with a fatal error if called. GLUT_LAYER_IN_USE Either GLUT_NORMAL or GLUT_OVERLAY depending on whether the normal plane or overlay is the layer in use. GLUT_HAS_OVERLAY If the current window has an overlay established. GLUT_TRANSPARENT_INDEX The transparent color index of the overlay of the current window; negative one is returned if no overlay is in use. GLUT_NORMAL_DAMAGED True if the normal plane of the current window has damaged (by window system activity) since the last display callback was trig- gered. Calling glutPostRedisplay will not set this true. GLUT_OVERLAY_DAMAGED True if the overlay plane of the current window has damaged (by window system activity) since the last display callback was trig- gered. Calling glutPostRedisplay or glutPostOverlayRedisplay will not set this true. Negative one is returned if no overlay is in use. DESCRIPTION
glutLayerGet retrieves GLUT layer information for the current window represented by integers. The info parameter determines what type of layer information to return. SEE ALSO
