Hi there - im trying to render some cubes that are imported via 3ds model class - and im putting the cubes in a VBO - sorry for the long code ( i dont know how to put conde in the message).... When putting lighing in the scene - the scene becomes darker - but no visible light like :P - i think im doing something wrong with the normals - becouse when i change the code from DrawDinamicVBO -(this code: glNormalPointer(GL_FLOAT,0, (char*)NULL); ) to glNormalPointer(GL_FLOAT,0, model.normalvector); i can see the light render but with very many artefacts. I also move the objects in the scene during rendering (not translate - actual moving of the vertex) Thanks! ///////////FUNCTIONS TO CREATE AND RENDER VBO void GL_Game::CreateDYNAMIC_VBO(CModel &model) { for(int i = 0; i<MAX_VERTICES; i++) { g_DiceManager.actorManager.playerCoordinates = model.VertexVector; g_DiceManager.actorManager.DefaultPlayerCoordinates = model.VertexVector; } //Vertex glGenBuffersARB(1, &model.playerVBuffer); glBindBufferARB(GL_ARRAY_BUFFER_ARB, model.playerVBuffer); glBufferDataARB(GL_ARRAY_BUFFER_ARB, model.k*3*sizeof(float), g_DiceManager.actorManager.playerCoordinates, GL_STREAM_DRAW_ARB); //Texture glGenBuffersARB(1, &model.playerTBuffer); glBindBufferARB(GL_ARRAY_BUFFER_ARB, model.playerTBuffer); glBufferDataARB(GL_ARRAY_BUFFER_ARB, model.k*2*sizeof(float), model.TextureVector, GL_STATIC_DRAW_ARB); //Normal glGenBuffersARB(1, &model.playerNBuffer); glBindBufferARB(GL_ARRAY_BUFFER_ARB, model.playerNBuffer); glBufferDataARB(GL_ARRAY_BUFFER_ARB, model.k*3*sizeof(float), model.NormalsVector, GL_STREAM_DRAW_ARB); } void GL_Game::DrawDYNAMIC_VBO(CModel& model) { glBindTexture(GL_TEXTURE_2D, model.texID); glBindBufferARB(GL_ARRAY_BUFFER_ARB, model.playerVBuffer); glBufferDataARB(GL_ARRAY_BUFFER_ARB, model.k*3*sizeof(float), g_DiceManager.actorManager.playerCoordinates, GL_STREAM_DRAW_ARB); glVertexPointer(3,GL_FLOAT,0,(char*)NULL); glBindBufferARB(GL_ARRAY_BUFFER_ARB, model.playerNBuffer); glNormalPointer(GL_FLOAT,0, (char*)NULL); glBindBufferARB(GL_ARRAY_BUFFER_ARB, model.playerTBuffer); glTexCoordPointer(2, GL_FLOAT, 0, (char *) NULL ); glDrawArrays(RENDER_MODE,0, model.k); }
