三角顶点缠绕顺序，从一面看是顺势针，那从另一面看就是逆时针，backface不是指你的脸，人家只是一种渲染优化，把你理应看不到的东西不做渲染。比如模型里有一个石头，你的视线经过两个面，背面的那个在你的这里顺时针，正面的三角形都是逆时针，你疑惑背面，担心背面的是有问题的，ok，如果你这时候从背面来看的话，你之前看到
b、关闭表⾯剔除(默认背面剔除) void glDisable(GL_CULL_FACE); c、用户选择剔除哪个面(正面/背面) void glCullFace(GLenum mode);//mode参数为: GL_FRONT、GL_BACK、GL_FRONT_AND_BACK,默认GL_BACK⽤户指定旋转顺序哪个为正面 void glFrontFace(GLenum mode);//mode参数为: GL_CW、GL_CCW,默认值:GL_...
假设“Primitives culled”的图形低,表明应用没有使用足够的裁剪。确认“backface culling”和“depth testing”都被激活。 假设“Primitives culled”的图形高,可能有下面几方面的原因: • 应用可能使用了太多的三角形 • 应用可能没有使用视锥裁剪 • 应用可能让Mali GPU做了太多的裁剪 6.1.5 检查是否使用了V...
在RenderScene函数中新增正背面剔除的开启/关闭操作 //开启/关闭正背面剔除功能if (iCull) {glEnable(GL_CULL_FACE);//以下两行是默认的,可以不写glFrontFace(GL_CCW);glCullFace(GL_BACK);}else{glDisable(GL_CULL_FACE);} 到此,甜甜圈的正背面绘制异常问题就解决了 但是在旋转过程中,新的问题又出现了,甜...
Free camera. Fly around the geometry sent to the graphics card and enable/disable wireframe/backface-culling/view frustum render. Save and track textures. (1D,2D,3D,NVRect and p-buffer bound textures are supported.) Saving can be to TGA,PNG and JPG formats. ...
