这不起作用,它们是水平的而不是内联的
glClearColor( 1.0f, 1.0f, 1.0f, 1.0f );
AttachVertexShader( shader, "szescian_vs.glsl" );
AttachFragmentShader( shader, "szescian_fs.glsl" );
LinkProgram( shader );
glBindVertexArray( vertexVAO );
glGenBuffers( 1, &positionBuffer );
glGenBuffers( 1, &positionBuffer );
glBindBuffer( GL_ARRAY_BUFFER, positionBuffer );
glBufferData( GL_ARRAY_BUFFER, sizeof( position ), position, GL_STATIC_DRAW );
positionLoc = glGetAttribLocation( shader, "inPosition" );
glEnableVertexAttribArray ( positionLoc );
glVertexAttribPointer ( positionLoc, 3, GL_FLOAT, GL_FALSE, 0, ( void* ) 0 ); //here gDEBugger GL breaks on OpenGL Error
