Note that due to current architectural constraints, all activities share a single ofApp class and a single canvas. You cannot switch to different ofApp classes for drawing different activities as OpenFrameworks cannot currently hold multiple instances of the ofApp class in memory.

OpenFrameworks supplies a base activity called OFActivity when the following conditions suits the project:. In order to achieve one or both the objectives above, you need to notify OpenFrameworks yourself on certain events, just like the original OFActivity does it:. Transform feedback is a relatively new feature in opengl present since 4. It allows to store the output of a vertex, geometry or tessellation shader into a buffer object.

For example we can draw a sphere in an ofVboMesh, draw it using a vertex shader that deforms the vertices using a noise function and get the result in a new buffer, then we can assign that buffer to an ofVbo for drawing. This allows to do expensive transformations in the GPU only once, store them and then draw them instead of having to do the calculations every frame.

It also allows to do several steps of vertex shaders for example or to generate geometry with a geometry shader and then use a different vertex shader to draw….

The download for 0. That example generates a mesh with a certain number of points but without setting them at all then draws the mesh using a shader with a transform feedback which modifies the poitns to distribute them along the surface of a semi-sphere uniformly and sets each vertex color depending on their position. The resulting buffer is assigned to a vbo and drawn later in the draw function without having to calculate the positions every frame.

OpenGL provides an extension promoted to core in 4. You can even set a breakpoint while debugging inside ofGLUtils. Once the breakpoint is set the debugger will stop whenever a message happens and you can see in the stacktrace the original in your code that is triggering it.

This is useful to debug obscure GL bugs like buffers not correctly bound or similar problems which are really hard to debug usually. Sometimes we want to change the behaviour of that shader. To do so, since 0. It receives the final color of the fragment as parameter and returns the modified color which will be the final color assign to that fragment:.

That has several problems mainly if we want to add a class to listen to a mouse event we would be tempted to do something like:. Even worse if we try to put this class in a vector as before but register the event after we add it like:. Doing so would solve our problem if in the copy constructor we re-add the new copy as a listener as well. To solve this issues in 0. Now to listen to an event the preferred method is something like:.

Another way to work around this is to wrap the objects in a smart pointer before putting them in a vector but be aware that doing so allocates every object in non contiguous locations in the heap so some of the advantages of using a vector are lost.

If you need to add more than one listener to a class you can also use ofEventListeners :. Key event arguments now carry much more information than before. Until now a key event was just an integer with the ascii for the pressed key but from 0. Also when you receive a key event you can also check if a modifier is pressed at the same time using ofKeyEventArgs::hasModifier as in:. The callbacks in ofApp are still the simple ones that just receive the int key for key events and the position x and y and mouse button for mouse events but you can easily change them to:.

And finally since 0. Again since we are using ofEventListener the listener will be unsubscribed automatically when destroyed. Some of this utilities where already introduced in 0.
