I''ve got a wierd problem. I''m drawing a mesh, in which currently the Y axis coordinate of every vertex is 3. Yet for some reason, my mesh is skewed at 45 degrees to the X axis. It''s really wierd. Here''s the code in question. I generate my mesh like this: int numStepsLength = (int)(CLOTH_LENGTH / CLOTH_RES); int numStepsWidth = (int)(CLOTH_WIDTH / CLOTH_RES); int clothCounter = 0; // Step through all points for (float x = CLOTH_START_X; x < (CLOTH_LENGTH + CLOTH_START_X); x = (x + CLOTH_RES)) { for (float z = CLOTH_START_Z; z > (CLOTH_START_Z - CLOTH_WIDTH); z = (z - CLOTH_RES)) { cloth_points.push_back(); cloth_points[clothCounter].id = clothCounter; cloth_points[clothCounter].x = x; cloth_points[clothCounter].y = CLOTH_START_Y; cloth_points[clothCounter].z = z; cloth_points[clothCounter].v.dx = x; cloth_points[clothCounter].v.dy = CLOTH_START_Y; cloth_points[clothCounter].v.dz = z; clothCounter++; } } The actual mesh drawing is done like this: int numStepsLength = (int)(CLOTH_LENGTH / CLOTH_RES); int numStepsWidth = (int)(CLOTH_WIDTH / CLOTH_RES); glPolygonMode(GL_FRONT_AND_BACK, GL_LINE); // Now that we''ve done all the vector calculations and rubbish draw our quads glBegin(GL_QUADS); for (int i = 1; i < numStepsWidth; i++) { for (int j = 1; j < numStepsLength; j++) { glColor3f(1.0f, 0.0f, 0.0f); glVertex3f(cloth_points.x, cloth_points[i].y, cloth_points[i].z); glVertex3f(cloth_points[(i+(1*j))].x, cloth_points[(i+(1*j))].y, cloth_points[(i+(1*j))].z); glVertex3f(cloth_points[((i+(1*j))+1)].x, cloth_points[((i+(1*j))+1)].y, cloth_points[((i+(1*j))+1)].z); glVertex3f(cloth_points[(i+1)].x, cloth_points[(i+1)].y, cloth_points[(i+1)].z); } } glEnd(); Can anyone see anything I''m missing? Thanks, David
