LabLab


A few personal projects, technical tests, you are in the laboratory R&D. ..A pool of ideas thrown in bulk. This is where concepts are born and new projects. This is where I explore new techniques, I develop the components, I'm looking for solutions to problems often encountered...
Any suggestions ?

A simple test of Machine Learning (Unity 3d).The goal for the agent is to push the ball on the red block with the least bounces possible, the fastest, and without touching the ground.It was necessary to limit the erratic movements and the too large displacements (still a lot of work is necessary at this level). Nevertheless, a few hours of training were enough to obtain a success rate higher than 80%.

Little demo of augmented reality by object recognition. The object recognition is for this moment less precise than by marker, but it works pretty well.This has been done with Unity 3d (2017.3.1f1) and Vuforia.

The physic managment brings a lot to a VR scene. In this example, I've added a dynamic reaction to the object in order to simulate a rubber effect with MegaFier with Unity 3d (HTC Vive).

Interior lighting study with Unity 3d (2017.1f3). The news feature 'Progressive Lightmapper' is marvelous and makes gain a huge gain of time in tweakings. The PBR materials, and Post processing FX contributes in a great part to realism.
A (Windows) demo is downloadable.

Behind this barbarian word (Screen Space Reflection) hides a technique of dynamic reflection on 3d surface. The reflections are calculated in real time on the camera level. The effect is very efficient but limited to camera space only. Everything wich is behind the camera field of view, is not taken into account. Candela has just released v3 of their asset wich fix this issue in a certain way. The result is quite convincing. Here are some comparative screens.

Review of the Unity 5 new global illumination feature. The result is quite stunning and promises unprecedented levels of realism. In this review, the compare between the old version (without GI), and the new dynamic lighting. Notice how the indirect lighting illuminates the room in subtle ways.

The physique in Unity doesn't take into account the inertia. It only acts when a force is applied (collision or other). This test intends to simulate inertia by applying forces to the character's extremities.

Dynamic water test under Unity 3d. The duck is floating by using the principles of Archimedes. The water surface is controled in part by the module MegaFiers. Touch the surface of the water, and try to change its density with the slider... (Unity 3d webplayer needed).

I've declined the 3d model made in Zbrush a few weeks ago in a low poly version to try to get something similar in Unity. A good facture of sub sufrace scattering is difficult to get in real time, and the result is certainly not up to the original model precalculated, but the shaders transcribe well the glazed appareance. Let's play with the density for the most improbable results ... (Unity 3d webplayer needed)

Rendering test with Arion. This unbiased render engine is incredibly efficent since it uses both cpu and gpu(s). The rock was modeled with Zbrush and rendered with diffuse, displacement map, bump map, specular map. The result is quite interesting, and the render engine is excessively fast and easy to use so far.
