4 Linking Shaders to OpenGL OpenGL Extensions ARB_shader_objects ARB_vertex_shader ARB_fragment_shader OpenGL 2.0 Almost identical to using extensions Avoid extension suffixes on function names 7 Container for shaders Program Object Can contain multiple shaders Other GLSL functions GLuint myprogobj; myprogobj = glcreateprogram(); // define shader objects here gluseprogram( g myprogobj ); gllinkprogram( myprogobj ); 8
5 Reading a Shader Shaders are added to the program object and compiled Usual method of passing a shader is as a nullterminated string using the function glshadersource If the shader is in a file, we can write a reader to convert the file to a string 9 Shader Reader char *ReadTextFile( char *filename ) { FILE *fp; char *content = NULL; int count = 0; if( filename!= NULL ) { fp = fopen( filename, "rt" ); if( fp!= NULL ) { fseek( fp, 0, SEEK_END END ); count = ftell( fp ); rewind( fp ); } if( count > 0 ) { content = (char *)malloc( sizeof(char) * (count+1) ); count = fread( content, sizeof(char), count, fp ); content[count] = '\0'; } fclose(fp); } } return content; 10
6 Adding Shaders GLuint vshader = glcreateshader( GL_VERTEX_SHADER ); GLuint fshader = glcreateshader( GL_FRAGMENT_SHADER ); char *vsource = ReadTextFile( "simple.vert" ); char *fsource = ReadTextFile( "simple.frag" ); const char *vv = vsource; const char *ff = fsource; glshadersource( vshader, 1, &vv, NULL ); glshadersource( fshader, 1, &ff, NULL ); free( vsource ); free( fsource ); glcompileshader( vshader ); glcompileshader( fshader ); glattachshader( myprogobj, vshader ); glattachshader( myprogobj, fshader ); 11 New Project 12
