Wire-Frame 3D Graphics Accelerator IP Core
Project Monophony
================================================
Author: Kenji Ishimaru <kenji.ishimaru@prtissimo.com>
2015/09/30
Overview
------------------------------------------
This IP Core is a wire-frame 3D hardware accelerator.
Features:
- Hardware Geometry Engine and Rasterizer
- Model-View-Projection matrix transformation
- Clipping
- Back-face culling
- Viewport mapping
- Wire-Frame rasterization with 8 bit color
- DMAC for reading 3D object vertices
- support triangle format only.
(does NOT support triangle strip, point, line etc.)
- Screen size: up to 2014 x 1536(QXGA)
- Small logic consumption
- Low bandwidth requirement
The IP Core does NOT support:
- Memory clear DMAC
- Filled triangle rasterization
- Texture mapping
- Lighting
Additional resources:
- Sample FPGA system implementation (DE0)
- with original VGA controller
- Demo applications
- C API for controlling 3D scene
- 3D model convert script
For more details,
please see doc/3DGraphics_IPCore_Specification.pdf.
Directories
---------------------------------------
The directory structure looks as follows:
doc/ - Documentation
rtl/ - HDL source code
scenario/ - Simulation test benches
bin/ - Simulation scripts
sim_work/ - Simulation work directory
implement/ - FPGA implementation example (DE0)
tool/ - 3D model convert tool and sample.
clib/ - C API source code
demo_app/ - Demo applications
IP Core Source Code
----------------------------
The IP Core is written by verilog-HDL. The source code is Vendor independent.
does not require any Vendor specific module.
Simulation
----------------------------
scenario directory contains simple rendering bench.
the rendering result is converted to bmp file.
For more details, please see sim_work/readme.txt
FPGA Sample Implementation
----------------------------
FPGA system implementation sample is available.
The target board is DE0.
The project data is tested on Quartus II Version 13.1
For more details, please see implement/readme.txt
Graphics C API
----------------------------
clib/ contains C API source code for this IP Core.
The API controls 3D scene, and controls IP Core by register configuration.
For more details,
please see doc/3DGraphics_C_Library_Specification.pdf.
Demo Application
----------------------------
demo_app/ contains demo applications.
simple_cube: rotating cube demo
main_cubes: rotating cubes. matrix push/pop demo
main_bear: bear characters
main_hand: hand animation
Screen shots of these demos are available in screen_shot/
3D Data Tool
----------------------------
tool/objcnv.pl perl script convertes .obj format 3D data to
C float array format, and output as C header file.
For more details, please see tool/readme.txt
