Description
之前的版本做了 view matrix 忽略相机缩放
// Ignore scale
const transform = this._entity.transform;
Matrix.rotationTranslation(transform.worldRotationQuaternion, transform.worldPosition, viewMatrix);
viewMatrix.invert();
return viewMatrix;
但是 inv view matrix 却没有忽略缩放
/**
* The inverse matrix of view projection matrix.
*/
private _getInvViewProjMat(): Matrix {
if (this._isInvViewProjDirty.flag) {
this._isInvViewProjDirty.flag = false;
Matrix.multiply(this._entity.transform.worldMatrix, this._getInverseProjectionMatrix(), this._invViewProjMat);
}
return this._invViewProjMat;
}
如果相机的缩放不为 1 ，viewport 到 world 的空间变换会出错。
