danodus / polyphony

3D graphics rendering system for FPGA, the project contains hardware rasterizer, software geometry engine, and application middleware.

Polyphony: 3D Graphics Rendering System

Overview

Polyphony is a 3D graphics rendering system. Rasterizer is written in Verilog, and Geometry Engine is written in C.

• Vendor-independent RTL design.
• Interface: AXI4
• Tested on FPGA boards.
• GLES API is partially implemented.
• Baremetal demo applications.

FPGA Board

Polyphony is implemented and tested on Zedboard.

Verilog RTL Simulation

Tested Environment

OS: CentOS7.8

Verilog Simulator: Icarus Verilog version 11.0

Test Scenarios

simple triangle rendering

cd sim_work
../bin/run_iv.sh ../scenario/3d/simple_triangle.v 

After finishing the simulation, VGA rendering result(result.bmp) will be generated.

simple texture-mapped triangle rendering

cd sim_work
../bin/run_iv.sh ../scenario/3d/simple_triangle_tex.v 

After finishing the simulation, VGA rendering result(result.bmp) will be generated.

Running the demo on FPGA board
