Hi Hendrik

Did you work out how to do this ? I’m also interested.

[racket-users] pict3d and pixel maps for textures

[Hendrik Boom]

Is there a way to paste a pixel map (such as a .png ?) to
a face of one of the objects in pict3d?  If so, I haven't found it.

I'd like to paint the objects with interesting textures.

Re: [racket-users] pict3d trouble

[Matthew Flatt]

Thanks for the info!

The problem was not specific to 10.11 (obviously) and not related to GL
bitmaps. It was in the way Pict3D creates and hides a frame to get a
screen-compatible GL context. Between v6.3 and v6.4, I changed the way
`racket/gui` hides a frame on OS X, and the new way destroys the GL
context that Pict3D is trying to get.

One workaround is for Pict3D to not show and hide the GL-context frame
on OS X. (The show-and-hide step is still needed to initialize the
context on Gtk.) A better solution would be to more directly support
the creation of screen-compatible GL contexts, but I'll leave that for
another day.

For now, I've pushed a change to Pict3D, and the catalog should pick up
the change soon.

Re: [racket-users] pict3d trouble

[Matthew Flatt]

I see the same problem on my machine with v6.4 and 6.4.0.8, and not
with v6.3.

Using `pict3d/universe` works for me in all versions, but the Pict3D
snip that's shown in DrRacket doesn't. So, I think the problem must be
due to a change since v6.3 in `racket/gui` related to GL bitmaps. I'll
investigate more.

Are you running 10.11 (El Capitan)?

Great. In case Alex's email wasn't clear, you should be able to
reinstall (remove and install again) and it will work on your older
version (unless it doesn't work because of a problem that has been
fixed since we moved on from v6.2.1).

Can you say what version of Racket you are using?

will tell you

[racket-users] Pict3d general Racket help

[bre2159732]

Trying to run some of the default tests from pict3d (spaceship.rkt) resulted in 
this error. When I downloaded the pict3d package to Racket I got a lot of the 
same (if I remember correctly) directory errors. Is this most likely from how I 
installed racket to begin with?  Ubuntu 14.04 LTS

Re: [racket-users] Pict3d general Racket help

[Alex Knauth]

This is because pict3d requires racket/struct, which was only added in racket 
version 6.3. If you have an older version, you'll get this error. 

There should probably be a version exception for older versions that doesn't 
require racket/struct. Or would it be better to change pict3d to not rely on 
racket/struct and use unstable/struct instead?

Re: [racket-users] Pict3d general Racket help

[Alex Knauth]

I just added version exceptions for earlier versions of racket, pointing to a 
version that doesn't require racket/struct. So this should be fixed now.

[racket-users] pict3d

['John Clements' via users-redirect]

1) pict3d is Totally magnificent. Think I said this before.
2) New OS X mouse controls are excellent.
3) Doc bug (I think). You write

Shapes: visible 2D surfaces in 3D space. Surfaces are visible on only one 
side.”

I believe the first word and the first word of the second sentence should be 
the same, e.g.:

Shapes: visible 2D surfaces in 3D space. Shapes are visible on only one side.

or

Surfaces: visible 2D surfaces in 3D space. Surfaces are visible on only one 
side.

John
