Research & Development for efficient light culling in Autonomous Vehicle Simulation

Ansys is seeking a software engineer intern to join our Solvers team, based in Sophia Antipolis. Our product performs a wide range of roles, such as visualizing simulations, displaying massive datasets, rendering physics-correct frame/images, simulating physics-correct sensors (Camera, Lidar, Radar), etc. We are currently transitioning from OpenGL to Vulkan to take advantage of its power and allow us to integrate new complex features of the world such as lighting systems, the sky, and different weather conditions phenomena. As an intern, he/she will be working on challenging and advanced technology subjects and will also actively contribute to the transition to Vulkan.

/ Key Duties and Responsibilities

The goal of this internship is to be able to cull a point light where its intensity angle range does not impact the part of the scene seen by the camera.

Today our engine, based on Vulkan, can render large, scaled environments with a lot of geometries and lights. The different benchmarks made with our engine show that the lighting is critical for performance. The implemented cull-based method for lighting is not efficient enough. It does not cull every light illuminating the part of the scene inside the frustum of the camera. The method can be improved by culling the lights based on their intensity diagram, also called IES. First the internship will focus on a simple type of intensity diagram: the gaussian intensity diagram. Then if the new method is validated, the other types of IES will be covered.

/ Minimum Education/Certification Requirements and Experience

You are validating a Master 2 of software engineering or equivalent graduation certificate with high interest in image processing and rendering simulation.

/ Preferred Qualifications and Skills

Language: C#/C++, OpenGL (and/or Vulkan)
Skills: Math and image signal processing
