How to change vertices in a mesh // Interactive Artwork 1  |   Order by default Post by Hans // May 19, 2007, 4:07am Hans Total Posts: 13 I want to write a script that starts with making a copy of a certain cube, then change its position and rotation according to numbers in a file and also change the vertices to values from world coordinates given in the file. Then this will be repeated with another copy a. s. o. until end of file. Is there anyone who can give me some hints on how to do this? The first problem I hit is to find out how to get at the vertices of a mesh with tS7.5 scripting. The second is how to recalculate world coordinates to mesh coordinates. The third is how to read from a file with Jscript. (I am a total newbie to tS scripting apart from a little Python, but am rather experienced i Smalltalk programming, and somewhat in VisualBasic6.)

Definitely let me know if you need any help. Professor Khaos wrote the code I based it on, so he's another good forum member to ask. -Jack.

You've done a great thing here with much of it being your own work :) One thing I'll have to look into myself a bit more too might be normals manipulation. I just realized the other day that changing vertex locations in theory changes normals orientations too. There may be a way to interpolate normals as well though it won't be quite the same as linear interpolation as is the case with vertices. P.K. (aka Nightflight) Post by Jack Edwards // May 25, 2007, 3:13am Jack Edwards Total Posts: 4062 Doh, I forgot all about the normals! :o Looks like there's still work to do on the morpher script.... -Jack. Post by Hans // May 30, 2007, 7:00am Hans Total Posts: 13 In the tSMorpher script I find this: BaseMeshVerts = BaseMesh.GetVerticesStreamByName('Vertex Stream Data'); But I can not find any documentation about GetVerticesStreamByName, but GetVerticesStream()
