openGL三维网格坐标,旋转,缩放,灯光设置,纹理读取,模型读取(MFC单文档).doc

openGL三维网格坐标，旋转，缩放，灯光设置，纹理读取，模型读取（MFC单文档） 在我的MFC单文档项目中enableview.h和enableview.cpp负责上面的窗口建立，myopenglview.h和myopenglView.cpp主要是功能的实现 1.三维网格建立： void GLGrid(float pt1x, float pt1y, float pt1z, float pt2x, float pt2y, float pt2z, int num) { const float _xLen = (pt2x - pt1x) / num; const float _yLen = (pt2y - pt1y) / num; const float _zLen = (pt2z - pt1z) / num; glLineWidth(2.f); glLineStipple(1, 0x0303);//线条样式 glBegin(GL_LINES); glEnable(GL_LINE_SMOOTH); int xi = 0; int yi = 0; int zi = 0; //绘制平行于X的直线 for (zi = 0; zi = num; zi++) { float z = _zLen * zi + pt1z; for (yi = 0; yi = num; yi++) { float y = _yLen * yi + pt1y; glVertex3f(pt1x, y, z); glVertex3f(pt2x, y, z); } } //绘制平行于Y的直线 for (zi = 0; zi = num; zi++) { float z = _zLen * zi + pt1z; for (xi = 0; xi = num; xi++) { float x = _xLen * xi + pt1x; glVertex3f(x, pt1y, z); glVertex3f(x, pt2y, z); } } //绘制平行于Z的直线 for (yi = 0; yi = num; yi++) { float y = _yLen * yi + pt1y; for (xi = 0; xi = num; xi++) { float x = _xLen * xi + pt1x; glVertex3f(x, y, pt1z); glVertex3f(x, y, pt2z); } } glEnd(); } void CmyopenglView::ordination() { glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glEnable(GL_BLEND); glEnable(GL_POINT_SMOOTH); //设置反走样 glHint(GL_POINT_SMOOTH_HINT, GL_NICEST); //设置反走样 glEnable(GL_LINE_SMOOTH); glHint(GL_LINE_SMOOTH_HINT, GL_NICEST); glEnable(GL_POLYGON_SMOOTH); glHint(GL_POLYGON_SMOOTH_HINT, GL_NICEST); glRotatef(-45, 0.0, 1.0, 0.0); //网格 glPushMatrix(); glColor3f(0.9f, 0.9f, 0.9f); glTranslatef(-4, -4, -4); GLGrid(0,0,0,8,0,8,20); glPopMatrix(); glPushMatrix(); glTranslated(-4,4, -4); glRotatef(90, 1.0, 0.0, 0.0); glColor
