[Closed] getRadiosityMesh

Ok, I think I’m getting to understand this. The Method getRadiosityMesh only saves in memory a TriMesh of the node selected. I came to this conclusion ‘cus if I use getNumFaces it returns the number of faces from the selected node, so if I do this:

getNumFaces $

and I have a box selected with 8 vertex it will only return it has 12 faces. But if I type this:

getNumFaces (radiosityMeshOps.getRadiosityMesh $)

it returns 389 faces, the number of faces that my radiosity mesh has. So if this can be possible, then maybe I will need to create a new mesh and then get the index of vertex or something like that to get the mesh and us it to anything I want. I’m new in this so I’m sorry if maybe I sound a little crazy, hehe, my apologies.

Hey sorta on the same topic, the radiosity mesh is loaded into memory, i notice that max is ALOT faster to use, is there a way to do something similar with the click of a button, load the scene mesh into memory so I can preview faster?

Also is there a way to make my own “Assign Vertex Color” script for the radiosity, as the max one doesnt work with the following…

callbacks.addScript #radiosityProcessDone "fnDoSomething()" id:#radiosityDone

fn fnDoSomething =
(
				callbacks.removeScripts #radiosityProcessDone id:#radiosityDone

				select $Teapot01

				mySelection = getcurrentselection()

				AssignVertexColors.ApplyNodes $ -- crashes on this line here! buy why?!
)

Thank you both for the answer!!!

Thanks master Bobo. So then, I was thinking on get the entire mesh as indexed vertex when there is a simple process. Thank you! This forum is really full of masters, but that’s nothing, the important of CG Society is that every body else shares their own researchs, doubts and questions.

Gibbz,

I ran the Bobo’s code and it worked. You just need to add a VertexPaint modifier to the new mesh, select Vertex Color Display from the Vertex Color Display Controls and that’s all.

The only thing that every body need to do is: to generate new code to select or get a selection, add it to a list and then get their meshes or anything one needs to. This is really a good advance to Max, it allows to customize your tools as you want to. I’m sorry, MAXScript is awsome!!

okay so ive been going about assigning vertex colors wrong? Instead of assigning them to my original mesh, i should apply the vertex colors to the radiosity tri mesh, and then this becomes my new mesh?

Ill have a little mess with it tonight, see if Im understanding it right

EDIT: ok i see whats happening now… is there something simmilar to .mesh but for editable poly, or should i just convert my mesh to editable poly after its done?

Cheers!

You can read .mesh from any geometry incl. EPoly, but you can assign to it only if it is an EditableMesh. So you can collapse your object to EMesh and assign the radiosity result to it. Then you can convert back to EPoly if you want, but since you are hardly going to edit it, it would be pointless and approx. 4 times slower to display in the viewports anyway…

Is editable poly 4x slower than editable mesh to display? Is there any reason for this? Or somewhere where i can find more info on it.

Thanks

okay cool, this should be a big help
