VRML 1.0 texture import problem

[Larry Edwards]

Hello,

I'm trying to import a VRML 1.0 model that has a texture file reference in it, i.e.:

Texture2 { filename "/home/ledwards/foo.jpg" }

The model geometry loads fine but I don't see any texture on import. Also, if I then export there is no texture reference in the file. I've tried both JPEGs and SGI rgb format, I can't get either to work.

I've also tried to load a VRML 1.0 file with an embedded texture, i.e.:

Texture2 { image 0x00 0x01 ... 0x12 }

and I see the status messages:

Importing VRML1 file
Assembling AC3D structure...

and then ac3d hangs. Is there a way to make this work (I have "Output VRML textures" turned on in the Files Settings).

I'm using a dual Xeon cpu Dell Precision 650, with an NVIDIA Quadro FX 3000 graphics board. AC3D prints out the following on startup:

OpenGL 1.4.0 NVIDIA 44.96 by NVIDIA Corporation, renderer: Quadro FX 3000/AGP/SSE2

I'm using the evaluation version of AC3D... if this can be done, you'll have one very happy new customer.

Thanks!

I just found the Objext Texture menu item and tried loading the texture manually as a separate step. That did cause a change in color, but still no texture.. probably the texture coordinate mapping is wrong, but I couldn't seem to make any change that produced a correct result.

I forgot to mention one thing, the object being loaded is an indexed face set... a terrain mesh.

Thanks for any help,

Hi Larry,

You need the jpeg plugin in order to load a jpeg texture (and use of plugins requires an AC3D licence).

If you change your texture to a .gif (or rgb), then edit the name in the vrml file, it should be OK.

Inline textures are not supported but it shouldn't hang - thanks for reporting that.

Hi Andy,

Actually .rgb was the first thing I tried. I just tried .gif and still no luck. I checked again to make sure that texture is turned on in the Ortho and 3d menus, and it was.

I also tried exporting to VRML1 (also tried VRML2) and no texture shows up in the file.

Anything else I should try?

Thanks!

Larry,

I looked and found a problem in the VRML parser - it means that 4.0 doesn't load textures.

I've fixed this for the next release. If you need me to convert any of your VRML files into AC3D format, let me know.
