Hy . I have implemented a polygon class . All work fine with one poly, but with more polygon something don't work. this is the draw function , the vertex and the faces are ok , i have controlled 34234234234 times , but.. I ask you if the draw function(the opengl sintax)have somthing wrong void CPolygon::Draw() { FACE* ptrFace = m_PolyData->m_faces; INDEX* ptrIndex = NULL; int nIndexCount = 0 ; int ixface=1; glPolygonMode(GL_FRONT_AND_BACK, GL_FILL); int nfacesCount = m_PolyData->m_nFacesCount; while(nfacesCount -- )//the number of face of the polygon { ptrIndex = m_PolyData->m_faces[nfacesCount].pIndex; nIndexCount = m_PolyData->m_faces[nfacesCount].nCount; glPushMatrix(); glBegin(GL_POLYGON); while(nIndexCount--)// number of vertex of the face { int pIdx =m_PolyData->m_faces[nfacesCount].pIndex[nIndexCount].nVertex;// index of the vertex GLfloat f1 = m_PolyData->m_vertexs[pIdx].val[0]; GLfloat f2 = m_PolyData->m_vertexs[pIdx].val[1]; GLfloat f3 = m_PolyData->m_vertexs[pIdx].val[2]; glVertex3f(f1,f2,f3);//vertexs coord at index } glEnd(); glPopMatrix(); } thanks
