QUESTION

java-processing floating point rounding error, how to keep radians rational

Asked 2021-Jan-12 at 03:24

I have modified this arcball class so that every call to arcball.rollforward(PI/180); rotates a matrix 1 degree. I have tried to set it up so arcball.rollback() is called with the accumulated float rotatebywithincludedfloaterror but it has had the same degree error as rolling back 360 degrees without the float error. this is how far it is off after 1000 full rotations, it should be a 1:1 reflection of the top cube over x

here is main function with a loop of 1 * 360 degree rotation and framerate for testing (set framerate to 900 for multiple rotations so it dose not take forever)

how to apply lighting to .obj file on pyopengl

Asked 2020-Sep-12 at 05:17

i implement arcball with an object from .obj file in the center when i try to implement lighting, the object show strange behaviour

when i turn the object slightly, the object deconstruct and suddenly show the back side

this behaviour doesn's come up until i implement lighting based on this How to correctly add a light to make object get a better view with pygame and pyopengl

this is what i do regarding the lighting impelementation

You have to enable the Depth Test. Enable the depth test before the application loop:

I'm currently working on a STL file viewer. This one use an Arcball camera :

To provide more features on this viewer (which can handle more than one object) I would like to implement a click select. To achieve it, I have used picking(Pseudo code I have used)

At this time, my code to check for a any object 3D between 2 points works. However the conversion of mouse position to a correct set of vector is far away from working:

I have found what's wrong, the return vec3 should be made by dividing each component by the perspective instead of being multiply by it. Here is the new UnProject function :
