 | | Do I use Dat2AutoCAD or is there a better way?
|
| For a project I am working on, I need a picture of a datapad (which I posted to .models) with text displayed on its screen (and I don't mean a perfect front view). I rendered the model in POV-Ray, but have no idea of how to get the text on it, (...) (23 years ago, 12-Mar-01, to lugnet.cad.ray, lugnet.cad.dev)

| POV-Ray can use bitmaps as surface textures. I've never done this myself, but I've seen it done. -John Van "Ryan Farrington" <ryanjf@ifriendly.com> wrote in message news:002501c0ab09$c8...dly.com... (...) (23 years ago, 12-Mar-01, to lugnet.cad.ray, lugnet.cad.dev)

| Ryan, Put the image_map inside a pigment statement, which is in turn inside the object statement. Like this: object { _screen_ pigment { image_map { gif "classicspacelogo.gif" interpolate 2 filter all 0.8 } } } I'm not sure what you want to do with (...)

| Thanks for the help, Coby! (...) I put this into the pov file and got something to appear on the object. But when I render it, all that you can see of the bitmap is a mess of gray pixels. Cheers, --Ryan (23 years ago, 15-Mar-01, to lugnet.cad.ray)

| Hmmm, a mess of grey pixels isn't good, but at least something appeared on the object so that's a start. I think the next step would be to check the scaling and translation of the map. Here's a pertinent paragraph from the docs: // By default, the (...) (23 years ago, 15-Mar-01, to lugnet.cad.ray)
