Rendering on FPGA

An implementation of 3D renderer on Terasic DE2-115 FPGA board

Requirements

• Quartus 16.1
• DE2-115 FPGA board

Description

Real-time 3D Renderer on DE2-115 using NIOS II

Demo: https://www.youtube.com/watch?v=2jhcZfhmaCM

Running a simple 3D rendering program on DE2-115

Currently using Nios II w/ Floating Point Hardware 2

Program written in ANSI C

Rendering is based on rasterization, which is normally faster than ray-tracing.

Features

• Reading .obj model file from SD card
• Reading .png texture file from SD card
• Camera control with keyboard and mouse (Movement: WASD; View: IJKL or mouse)
• Resolution: 160x120 scaled to 640x480 VGA
• Frame rate: about 10~15 fps

Used libraries and resources

• lodepng: https://github.com/lvandeve/lodepng
• tinyobjloader-c: https://github.com/syoyo/tinyobjloader-c
• Some example code from Terasic DE2-115 CD-ROM
• SD Card controller from Altera University Program
