extract-frustum-planes
Returns a list of frustum planes from a given WebGL matrix (assuming the matrix is stored in the same format as used by gl-matrix).
Install
npm install extract-frustum-planes
Example
var getPlanes = require("extract-frustum-planes")
var glm = require("gl-matrix")
var m = glm.mat4.perspective()
API
require("extract-frustum-planes")(worldToClip[, zNear, zFar])
Extracts the frustum planes of the combined world to clip coordinate matrix for WebGL
worldToClip
is the concatenated model-view-projection matrix in the same format as expected by WebGL (ie compatible with gl-matrix)zNear
is the near clip plane distance as set bygl.depthRange
(default 0.0)zFar
is the far clip plane distance as set bygl.depthRange
Returns An array of 6 planes encoding the view frustum stored in the order:
left
right
top
bottom
near
far
