[Solved] Cinder native approach to multi-texture geoms?

[Gazoo]

Another good idea @paul.houx which I’ll keep in mind moving forward.

For anyone else reading along, what I’ve gathered, you can use Cinder’s Texture3d object, and set the format to GL_TEXTURE_2D_ARRAY, to use a 2d texture array.

In my case, I want one of the Cube’s textures to originate from an FBO, so using a Texture3d would likely include a costly call to update() the 3d texture every frame, making it less appealing than simply referencing a different sampler2d variable.

Last but not least for anyone wanting to use the Texture3d object, I don’t know if Cinder easily supports attaching 3d texture coordinates to its geom objects. Perhaps it’s possible to use a modifier like this:

Change texture coordinates of geom::plane

hey there everyone, I have something here that seems like it should be simple but I cannot work it out. I have a geom::plane in a batch; it goes through a nothing-special shader that takes a texture as in many of the example projects. it perfectly stretches the texture to fit the plane when drawn, but I want it to repeat the texture! I read in an earlier post that I need to give something somewhere in the program some texture coordinates outside the range of [0,1]. but, ciTexCoord0 is being s…

But I reckon the approach in the forum link above only modifies existing values, rather than extend them (i.e. from 2 to 3 floats).

Last but not least, I’m still investigating why rendering an FBO texture on Cinder’s geom::cube flips it backwards:

[Solved] Applying ColorTexture from FBO to a geom::Cube with unexpected results

I’ve rendered a scene into an FBO and then applied the texture directly to a geom::Cube with Cinders stock texture shader. Rendering the cube on top of the scene looks as follows: [Screenshot (32)] My biggest surprise is that the texture is backwards on all sides. Is this normal? I know that flipping the texture coordinate mapping would solve this, but I feel like mapping a the FBO texture directly on to a cube without fiddling with the texcoords would have the texture not be backwards? Any…

Cheers for all the awesome ideas and approaches to multi-texturing geometry!
