working with samples in CHOPs. This is applied to GPU instancing, LEDs, lasers and so much more

In TD 099, during section 12.7.2,
The following snippet cause errors:

// move point from object space to screen space and output to gl_Position
vec4 worldSpaceVert = TDDeform(newPosition);
vec4 camSpaceVert = uTDMat.cam * worldSpaceVert;
gl_Position = TDCamToProj(camSpaceVert);

TD 099 doesn't use uTDMat.cam anymore. it needs to be replaced by uTDMats[0].cam, as we have an array of cameras in TD 099. However, solving that is not enough, TDCamToProj() doesn't exist anymore.

What did the trick for me was to use:

gl_Position = TDWorldToProj(TDDeform(newPosition));

Noticed this when printing out parts of the book. With some images the red overlays (text/arrows/etc) are almost impossible to see because their 'value' (the V in HSV) is almost identical to the background gray color. So when printing in B&W they disappear. An example of this is the image in section 2.6.

Recommend trying a different brighter value (since dark backgrounds in most cases), maybe even white since bright pink might not be what you are going for ;)

If you agree I'd be happy to make the changes as I see you've included the .psd files for easy editing.

Shadertoy has switched the uniform iGlobalTime to simply iTime for all their shaders. Chapter 12 still refers to iGlobalTime.

As Intel stopped support for Realsensecamera F200 the drivers are no longer available.
RealsenseCHOP runs on RuntimeSDK 6.0.21.6598.

Where can one find that driver?

Thanks.
