comment How do I render .dae models?
+1. I have written a COLLADA importer before and my only advice on it is: don't. Even if all you ever want to import is COLLADA, get ASSIMP because their resultant DOM is simpler than that of a COLLADA scene, and they have post-processing optimisations built in. If you re-he-he-he-heally want to process the DAE yourself, skip the parsing stage and go straight for one of the classes produced by XSD.exe then at least you can use Intellisense to help navigate that maze!

comment How can I view an R32G32B32 texture?
I may be being a little dense but why can you not get the contents of the texture (by mapping it, or copying to staging resource), then bit-bang the raw content into a block of memory, process the pixels from R32R32R32 into U8U8U8 then just use that block as the source for a bitmap then view and save this?

comment I can't figure out how to animate my loaded model with Assimp
@AlexanderGessler, Thanks! Not at all, go ahead - I'm glad after writing all that it is of use :)

comment What calls trigger a new batch?
@Nock - I had in my mind a constant buffer since that is most likely to require change in content between objects.

comment Could someone explain why my world reconstructed from depth position is incorrect?
@yuumei; I believe so as they are written by the pipeline which includes the perspective divide. My implementation was in OpenCL but there should be no need to use an interim buffer, you just need to pass in the camera properties which were used to generate the picture plane your depth values are in.

comment What is a simple deformer in which vertices deform linearly with control points?
This has the best results of anything I have tried so far, but this is without a proper 'physics mesh' (its just the main mesh with me culling everything with the wrong normal). Experimentation will tell how much milage this will have when I figure out how to generate the physical mesh... (At least this application of it should be an interesting write-up if I ever get it to work! ;))

comment What is a simple deformer in which vertices deform linearly with control points?
@teodron, Thanks for that link! (to anyone else, remove the ] at the end of the url to read it) Those results are a lot more impressive than previous papers' use of vector fields. I am understanding more and more just what the scope of this subject is as I research it for my problem. At the moment I calculate the inverse of the proportion of each distance, to the sum of the distances of the control points to the vertex, then normalise the results to get the weights.

comment What is the most effective way to create a set of collision points for an aribitrary mesh?
@Byte56, Hi, I have tried to find another version but that FTP site seems to be the only place. Google has a document viewer, maybe it will be easier to read it via that?: docs.google.com/viewer?a=v&q=cache:lK7DaJV_ogEJ:ftp://…
