openGL三維網(wǎng)格坐標(biāo),旋轉(zhuǎn),縮放,燈光設(shè)置,紋理讀取,模型讀取MFC單文檔

openGL 三維網(wǎng)格坐標(biāo)，旋轉(zhuǎn)，縮放，燈光設(shè)置，紋理讀取，模型讀取（MFC單文檔）在我的 MFC 單文檔項(xiàng)目中 enableview.h 和 enableview.cpp 負(fù)責(zé)上面的窗口建立，myopenglview.h 和 myopenglView.cpp 主要是功能的實(shí)現(xiàn)1.三維網(wǎng)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);/線條樣式glBegin(GL_LINES);glEnable(GL_LINE_SMOOTH);int xi = 0;int yi = 0;int zi = 0;/繪制平行于 X 的直線for (zi = 0; zi InvalidateRect(NULL, FALSE);return CView:OnMouseWheel(nFlags, zDelta, pt);void enableview:OnMouseMove(UINT nFlags, CPoint point)/ TODO: 在此添加消息處理程序代碼和/或調(diào)用默認(rèn)值if (nFlags du += point.x - oldmx; /鼠標(biāo)在窗口 x 軸方向上的增量加到視點(diǎn)繞 y 軸的角度上，這樣就左右轉(zhuǎn)了h += 0.03f*(point.y - oldmy); /鼠標(biāo)在窗口 y 軸方向上的改變加到視點(diǎn)的 y 坐標(biāo)上，就上下轉(zhuǎn)了if (h15.0f) h = 15.0f; /視點(diǎn) y 坐標(biāo)作一些限制，不會(huì)使視點(diǎn)太奇怪else if (hOnDraw(this-GetDC(); /重繪界面else if (nFlags oldmy += point.y - oldmy;glTranslatef(oldmx, oldmy, -0.1f);this-OnDraw(this-GetDC();oldmx = point.x, oldmy = point.y;else oldmx = point.x, oldmy = point.y;/OutputDebugString(_T(“mouse upn“);/CView:OnMouseMove(nFlags, point);4.鍵盤(pán)相應(yīng)旋轉(zhuǎn)縮放BOOL CmyopenglView:PreTranslateMessage(MSG* pMsg)if (pMsg-message = WM_KEYDOWN) / If a keydown messageif (pMsg-wParam = _T(W)this-rotate_x += 6.0;if (this-rotate_x 360)this-rotate_x = -360;this-InvalidateRect(NULL, FALSE);if (pMsg-wParam = _T(X)this-rotate_x += 6.0;if (this-rotate_x rotate_x = 360;this-InvalidateRect(NULL, FALSE);if (pMsg-wParam = _T(A)this-rotate_y -= 6.0;if (this-rotate_y rotate_y = 360;this-InvalidateRect(NULL, FALSE);if (pMsg-wParam = _T(D)this-rotate_y += 6.0;if (this-rotate_y 360)this-rotate_y = -360;this-InvalidateRect(NULL, FALSE);if (pMsg-wParam = _T(Z)this-rotate_z -= 6.0;if (this-rotate_z rotate_z = 360;this-InvalidateRect(NULL, FALSE);if (pMsg-wParam = _T(E)this-rotate_z += 6.0;if (this-rotate_z 360)this-rotate_z = -360;this-InvalidateRect(NU
