Viewing frustum - Wikipedia
网页A view frustum. The appearance of an object in a pyramid of vision. When creating a parallel projection, the viewing frustum is shaped like a box as opposed to a pyramid. In 3D computer graphics, a viewing frustum[1] or view frustum[2] is the region of space in the modeled world that may appear on the screen; it is the field of view of a ...

网页视图平截锥体（view frustum）几何体数据的生成. 要绘制view frusutum，首先需要确定frustum形状的几何数据。. 由于我们只是要绘制出frustum的基础轮廓，因而我们会准备相关线段的顶点以及顶点色彩属性数据。. 我们对顶点数据的准备会分为两个步骤。. 1. 根据眼睛 ...
Manual: Understanding the View Frustum - Unity
网页Understanding the View Frustum. The word frustum refers to a solid shape that looks like a pyramid with the top cut off parallel to the base. This is the shape of the region that can be seen and rendered by a perspective camera A component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen ...

网页本文章介绍了如何 从投影矩阵（ProjectionMatrix）推导，得到视锥体（Frustum）的六个面的面方程，并且判断一个 点（point）是否在视锥体范围内，或者包围球（Bound ing Sphere） 是否与视锥体相交。. 当然，我们也可以通过 ViewMatrix，将平面萃取到摄像机坐 …
网页the viewing plane and virtual space represents the viewing frustum or view frustum. The view frustum represents the region of space that is projected onto the viewing plane. It defines the field of view of the virtual camera defining the projection. In OpenGL, the view frustum shape is set on the GL_PROJECTION stack and the glOrtho command ...

View Frustum Culling - Lighthouse3d.com
网页The view frustum is the volume that contains everything that is potentially (there may be occlusions) visible on the screen. This volume is defined according to the camera’s settings, and when using a perspective projection takes the shape of a truncated pyramid.
Understanding the View Frustum - Unity 手册
网页Understanding the View Frustum. The word frustum refers to a solid shape that looks like a pyramid with the top cut off parallel to the base. This is the shape of the region that can be seen and rendered by a perspective camera. The following thought experiment should help to explain why this is the case.
网页Projective Frustum Clip Equations Generalizes clip cube as a projective space Uses (x c,y c,z c,w c) clip-space coordinates Equations -w c ≤ x c ≤ +w c-w c ≤ y c ≤ +w c-w c ≤ z c ≤ +w c Notice Impossible for w c < 0 to survive clipping Interpretation: w c is distance in front of the eye So negative w c values are “behind your head”
