76 | <para> | |
77 | <function>glShaderBinary</function> loads pre-compiled shader binary code into the <parameter>count</parameter> | |
78 | shader objects whose handles are given in <parameter>shaders</parameter>. <parameter>binary</parameter> | |
79 | points to <parameter>length</parameter> bytes of binary shader code stored in client memory. | |
80 | <parameter>binaryFormat</parameter> specifies the format of the pre-compiled code. | |

82 | <para> | |
83 | The binary image contained in <parameter>binary</parameter> will be decoded according to the extension | |
84 | specification defining the specified <parameter>binaryFormat</parameter> token. OpenGL | |
85 | does not define any specific binary formats, but it does provide a mechanism to obtain token | |
86 | vaues for such formats provided by such extensions. | |
87 | </para> | |
88 | <para> | |
89 | Depending on the types of the shader objects in <parameter>shaders</parameter>, <function>glShaderBinary</function> | |
90 | will individually load binary vertex or fragment shaders, or load an executable binary that contains an optimized | |
91 | pair of vertex and fragment shaders stored in the same binary. | |
