Research & Development for efficient light culling in Autonomous Vehicle Simulation

Ansys is seeking a software engineering intern to join its Sophia-Antipolis-based team that is a physics-focused real-time Sensors R&D team within the AVxcelerate product. Our product performs a wide range of roles, such as visualizing simulations, displaying massive datasets, renders physics-correct frame/images, simulate 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 of the real-time rendering team, he/she will be working in an outstanding environment and outstanding individuals. Moreover, he/she will be working on challenging and advanced technology subjects and will also actively contribute to the transition to Vulkan in the new engine.

/ 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 have 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
