Hello,
I'm rendering into an OpenGL offscreen framebuffer object and like to save it as an image. Note that the FBO is larger than the display size. I can render into the offscreen buffer and use it as texture, which works. I can "scroll" this larger texture through the display using an offset, which makes me confident, that I render in...
I really like the work that's done with processing (http://processing.org) but I'm more exposed to the .Net world and would like to stay there. Is there a library or sub-language within .Net that is very focused on being easy to use for artists?
Processing and OpenFrameworks excel because it's so easy to create animations and other visu...
Hi,
I've started to use XCode and it seems to work, well, most of it.
The annoying thing is it compiles all the source files, even those that didn't change, each and every time.
I'm getting the grips with openframeworks and I waste time compiling the openframeworks source files every time although they don't change.
Here are my IDE a...
Hello folks, I'm primarily a Flash AS3 dev, but I'm jumping into openframeworks and having trouble using 3D (these examples are in AS)
In 2D you can simulate an object orbiting a point by using Math.Sin() and Math.cos(), like so
function update(event:Event):void
{
dot.x = xCenter + Math.cos(angle*Math.PI/180) * range;
dot.y = y...

Hi,
I am trying to do a Z-Index reordering of videoObjects stored in a vector. The plan is to identify the videoObject which is going to be put on the first position of the vector, erase it and then insert it at the first position. Unfortunately the erase() function always causes bad memory access.
Here is my code:

I'm using c++ OpenFrameworks and ofx3dModelLoader to load in 3ds models that I've already created. This is working great. However I would like to smoothly transition models visually as the enter the frustum's back plane. I have fog working but would really like to fade the models in from transparency.
Is there any way to do this eithe...
The simple version of my project is rotating a sphere based on user input.
However my rotations get weird after multiple rotations in certain situations due to openGL's local coordinate system.
What I really need is to rotate based on a world/fixed coordinate system. Such that when I rotate the sphere once its rotation axes are not rota...
I am working in a project using openframeworks and I've been having some problems lately when writing XMLs. I've traced down the problem to a sprintf:
It seems that under certain conditions an sprintf call may write commas instead of dots on float numbers (e.g. "2,56" instead of "2.56"). In my locale the floating numbers are represented...
Hi all,
I am developing a simple multi touch table using only a projector and a web cam. I found out that i could use this Thumb and fore finger interface technique. but i don't have any clue of how to implement it. i think it can be implemented with OpenCV or OpenFrameworks and use with CCV. can anybody help me ?
Thanks,
