OpenGL/glisenabled(3) -- test whether a capability is enabled
|
|
cap Specifies a symbolic constant indicating a GL capability. |
|
OpenGL/glislist(3) -- determine if a name corresponds to a display-list
|
|
list Specifies a potential display-list name. |
|
OpenGL/glistexture(3) -- determine if a name corresponds to a texture
|
|
texture Specifies a value that may be the name of a texture. |
|
OpenGL/glistextureext(3) -- determine if a name corresponds to a texture
|
|
texture A value which might be the name of a texture. |
|
OpenGL/gllight(3) -- set light source parameters
|
|
light Specifies a light. The number of lights depends on the implementation, but at least eight lights are supported. They are identified by symbolic names of the form GL_LIGHTi where 0 < i < GL_MAX_LIGHTS. pname Specifies a single-valued light source parameter for light. GL_SPOT_EXPONENT, GL_SPOT_CUTOFF, GL_CONSTANT_ATTENUATION, GL_LINEAR_ATTENUATION, and GL_QUADRATIC_ATTENUATION are accepted. param Specifies the value that parameter pname of light source light will be set to.... |
|
OpenGL/gllightenv(3) -- specify fragment lighting environment
|
|
pname Must be GL_LIGHT_ENV_MODE_SGIX param Can be one of three values: GL_REPLACE, GL_MODULATE, or GL_ADD |
|
OpenGL/gllightmodel(3) -- set the lighting model parameters
|
|
pname Specifies a single-valued lighting model parameter. GL_LIGHT_MODEL_LOCAL_VIEWER, GL_LIGHT_MODEL_COLOR_CONTROL, and GL_LIGHT_MODEL_TWO_SIDE are accepted. param Specifies the value that param will be set to. |
|
OpenGL/gllinestipple(3) -- specify the line stipple pattern
|
|
factor Specifies a multiplier for each bit in the line stipple pattern. If factor is 3, for example, each bit in the pattern is used three times before the next bit in the pattern is used. factor is clamped to the range [1, 256] and defaults to 1. pattern Specifies a 16-bit integer whose bit pattern determines which fragments of a line will be drawn when the line is rasterized. Bit zero is used first; the default pattern is all 1's.... |
|
OpenGL/gllinewidth(3) -- specify the width of rasterized lines
|
|
width Specifies the width of rasterized lines. The initial value is 1. |
|
OpenGL/gllistbase(3) -- set the display-list base for glCallLists
|
|
base Specifies an integer offset that will be added to glCallLists offsets to generate display-list names. The initial value is 0. |
|
OpenGL/gllistparametersgix(3) -- specify display list parameters
|
|
list Specifies the integer name of the display list whose parameters are to be set. pname Specifies the symbolic name for a display list parameter. Must be GL_LIST_PRIORITY_SGIX. param Specifies a single value for the selected display list parameter. If pname is GL_LIST_PRIORITY_SGIX, then the value must be a display list priority in the range [0.0, 1.0]. |
|
OpenGL/glloadidentity(3) -- replace the current matrix with the identity matrix
|
|
glLoadIdentity replaces the current matrix with the identity matrix. It is semantically equivalent to calling glLoadMatrix with the identity matrix ( ) 1 0 0 0 | | | 0 1 0 0 | | | 0 0 1 0 | | ( 0 0 0 1 ) but in some cases it is more efficient. |
|
OpenGL/glloadmatrix(3) -- replace the current matrix with the specified matrix
|
|
m Specifies a pointer to 16 consecutive values, which are used as the elements of a 4 x 4 column-major matrix. |
