Detailed Description

template<typename T>
class UT_Matrix4T< T >

This class implements a 4x4 fpreal matrix in row-major order.

Most of Houdini operates with row vectors that are left-multiplied with matrices. e.g., z = v * M As a result, translation data is in row 3 of the matrix, rather than column 3.

Turn this matrix into the "closest" rigid transformation (only rotations and translations) matrix.

It uses polarDecompose and then negates the matrix if there is a negative determinant (scale). It returns false iff polarDecompose failed, possibly due to a singular matrix.

This is currently the one true way to turn an arbitrary matrix4 into a rotation and translation matrix. If that ever changes, put a warning here, and you may want to update UT_Matrix3::makeRotationMatrix too.

Create an orthographic projection matrix with the given parameters. This can be used to project points onto the so-called NDC coordinates of a camera. For example, given a point P (in the space of a camera):

UT_Vector3 ndc;
UT_Matrix4R proj;
proj.orthographic(zoom, 1, image_aspect);
ndc = P * proj;
  • zoom
    The zoom for the lens
  • orthowidth
    An additional "zoom" factor
  • image_aspect
    The resolution of the image
  • pixel_aspect
    The pixel aspect (the aspect ratio of pixels)
  • near,far
    The near/far clipping planes
  • window
    The offset for the projection window.

The projection transform will transform the z coordinate of the camera space point such that the near coordinate will map to 0 and the far coordinate will map to 1. That is n dz.z = fit(P.z, near, far, 0, 1); . Thus, if the near/far are set to 0/1, the NDC z-coordinate will be the same as the camera space z. If the near/far are set to 0/-1, the Z coordinate will be negated.

Note
Sometimes the zoom is expressed in terms of focal and aperture. In this case: zoom = focal/aperture
Sometimes the image_aspect is expressed in terms of xrex and yres. In this case: image_aspect = xres / yres
To make a single transform from world space to NDC space given a camera matrix and a projection matrix, you would use worldToNDC = worldToCamera * projection;

Perform the polar decomposition of the 3x3 matrix M into an orthogonal matrix Q and an symmetric positive-semidefinite matrix S. This is more useful than explode() or extractRotate() when the desire is to blend transforms. By default, it gives M=SQ, a left polar decomposition. If reverse is false, then it gives M=QS, a right polar decomposition.

This method is similar to the UT_Matrix3 version except it only operates on the upper-right 3x3 portion.

Precondition
The upper-right 3x3 portion of *this is non-singular
Postcondition
The upper-right 3x3 porition = Q, and if stretch != 0: *stretch = S.
Returns
True if successful
