Hi, I'm trying to draw a red circle into a fbo and then use it as a texture for a box shape.
I tried the below code and fbo.draw() works fine but I could not bind the texture into a box.
//-------------------------------------------------------------- void ofApp::setup(){ fbo.allocate(200, 200, GL_RGBA); fbo.begin(); ofClear(255, 255, 255, 150); ofSetColor(ofColor::red); ofDrawCircle(100, 100, 100); fbo.end(); ofDisableArbTex(); ofEnableDepthTest(); mesh = ofMesh::box(200, 200, 200); } //-------------------------------------------------------------- void ofApp::update(){ } //-------------------------------------------------------------- void ofApp::draw(){ fbo.draw(0, 0); ofTranslate(ofGetWidth()/2, ofGetHeight()/2); float degrees = ofGetElapsedTimef()*10; ofRotateX(degrees); ofRotateY(degrees); ofRotateZ(degrees); fbo.getTexture().bind(); mesh.draw(); fbo.getTexture().unbind(); }What is wrong with my code?
Thanks in advance.

I create a class "Ball" . In this I created the "Ball :: keypressed" and "Ball :: keyReleased" methods. Ex....
void Ball::keyPressed(){ if(key== OF_KEY_RIGHT){ right += 5; } else if (key== OF_KEY_LEFT){ left -= 5; }I would like to make them run with the keys, calling them directly from ofApp. Ex:
void ofApp::keyPressed(int key){ Ball.keypressed(); }I have no idea how to do it. Can someone help me?

Hey OF forum,
Attempting to get Artnet functionality working for a project, has anyone had success on windows 10? With the ofxArtnet addon I get a console error message "[ error ] node is not found "
Tested with firewalls disabled as recommended. Was able to successfully get artnet working using MadMapper.
Any help would be appreciated.
Thanks

Hi,
I installed oF + mysys2 and Qt with QtCreator on a new Windows 10 pc exactly the same way I did some monts ago on the old one.
On the old pc everything works fine.
On the new one I can succesfully recompile and execute a project I already developed on the old pc.
But if I start from scratch a new project in the new pc from QtCreator->File ->New File or Project->openFrameworks and then correctly setup project path, oF library folder and addons, I get an error from the editor.
In the sidebar a new .qbs project is actually started but I get this message:
! Cannot lock build graph file 'C:/Users/info/OneDrive/Dokumente/Error in " Util.asciify("build-untitledTEST-Desktop-Debug")": TypeError: Property 'asciify' of object Core::Internal::UtilsJsExtension(0x737eb88) is not a function/qtc_Desktop_94451bc9-debug/qtc_Desktop_94451bc9-debug.bg': Failed to create directory.And obviously can't start the new project because except.qbs file everything else is missing and the error completely locks the editor.
Anyone have some ideas about what does it mean and how can be fixed?
Of course for now I can take an old project, copy and rename it, set the new paths, clear the source files and use it as starting point for new projects, but... you know!
Thank you in advance!

Hi,
I've been looking for a water color shader implementation exampe or some guidance on how to achieve a similar effect. I'm planning to have a mouse-follower (simple brush) based interaction in the end. Unfortunately google hasn't been very rewarding so far.
An ideal visual representation for me would be something like this:

Hello,
In my project I have a rotating sphere, an ofEasyCam and a series of particle emitters on the surface. I want to draw the "trail" of the particle, like on the 2D example, with ofFbo: what's the best way to use it? I have done little experiment, but it was all terribly wrong.Thanks for your help!

Hi all,
I'd like to load a group of .jpg files from a single folder on the web. Does anyone have any suggestions for this? I've tried and failed with ofDirectory and a path like "http://myWebSite.com/myImageFolder", though it works great for any folder on my system drive. I've successfully used ofURLFileLoader for a single file (like in the graphics example), but not for a group of them in a folder (assuming that their names are unknown at compilation). And image.load("http://myWebSite.com/myImageFolder/myImage.jpg") works just fine, but this approach also requires that the file names are known ahead of time, rather than being deduced from the actual contents of the folder. Perhaps there is an addon for this task? Any help is greatly appreciated and thanks a bunch!

Hi guys,
I'm using a text document to make a vector of colors. Now I want to print these colors in blocks of 5x5 pixels.
This makes a zoomed in version of the individual pixels that I can compare to my LED-matrix. I've researched for quite a while but can't seem to find a way to do this. Does anyone know how to do this?Thanks!

Hello all!
I am using ofxThreadedImageLoader to load a series of images on demand several times throughout my project. Does anyone have ideas or could point me in the right direction to tell when ofxThreadedImageLoader is finished loading? The thread seems to never stop running, even after the images are loaded.

Circle Variations by Perlin Noise
Any clues on how to make something similar? I've drawn circles with tangents, etc. from the ofBook but its really the slow rotations and circle trails that are catching my n00b eye.
thanks ^.^

Hi all,
I am working on embedding a browser into OF app, which seems a smart way of integrating the easy layout possibilities of HTML in an OF-powered app. I searched for quite long, and like to share my experience. I hope you people do share yours:
(All is windows VS, which is a requirement for me I am afraid)
- ofxAwesomiumPlus was quite easy to include. It works rather well and seems stable. Still checking on this, I'll update if I know more. Big drawback of using Awesomium is that the webpage of Awesomium is gone for quite a while. Wiki still exists, but I do not know if Awesomium is still maintained. Some people say it's dead? Anyone knows hard facts?
Also, as far as I know there is no 64 bit version.- ofxCef. I found some quite up to date forks (and a lot of posts on the topic) but did not succeed in compiling the example yet (although compiling cef itself seems to have been successful). I'll look further into this and eventually update this - but I'd appreciate your experience.
Is there other possibilities working with windows? What is confusing me it that many posts on the topic I found are rather old and it is difficult to find up-to-date information. Do I miss something? Or is it just of minor importance for most of you? For my industry this would be a major feature.
Thanks all & have a great day!

Can anyone offer me any working example?

Hi, I'm trying to find the center x,y position of each drawn letter.
For example, if I draw "Hello" on the screen, I want to find out 5 different positions that points to center of each character.
I tried to simply get the bounding box of the text and divide it by the number of letters but it doesn't seem to be accurate enough.
Here's my test code.
//-------------------------------------------------------------- void ofApp::setup(){ ofSetBackgroundColor(255); font.load("/Users/cuinjune/Library/Pd/ofelia/DejaVuSansMono.ttf", 30); } //-------------------------------------------------------------- void ofApp::update(){ } //-------------------------------------------------------------- void ofApp::draw(){ string text = "Hello World"; ofSetColor(0); font.drawString(text, 100, 100); ofNoFill(); ofSetColor(255, 0, 0); ofRectangle bb = font.getStringBoundingBox(text, 100, 100); ofDrawRectangle(bb); float startingX = bb.x; float startingY = bb.y; float letterWidth = bb.width / text.length(); float letterHeight = bb.height; for (int i=0; i<text.length(); ++i) { ofDrawRectangle(startingX + (i*letterWidth), startingY, letterWidth, letterHeight); } }And this is the result.
But as you can see, the letters are not evenly distributed so my method isn't really accurate.Any idea how to do it more accurately?
Thanks in advance!
