3D viewer for raspberry or other GLES/OpenGL linux using the Open Asset Import Library pi3d is an openGL/GLES viewer. The goal of this project is to make it possible to view 3d models on a raspberry.
// This connects to a ESP8266 with the sketch loaded in the sketch direcory Now it also connects to a ESP8266 with a BNO055 sensor. https://learn.adafruit.com/bno055-absolute-orientation-sensor-with-raspberry-pi-and-beaglebone-black/hardware?view=all
It uses assview and glm included as a submodules. Try
git submodule init
git submodule update
Here are some other dependencies
glm, Get glm, necessary to build the pi3d viewer. Headers only library. https://www.opengl.org/sdk/libs/GLM/
glfw, http://www.glfw.org
glew, This does not support GLES. This dependeny will be removed.
On archlinux you install the dependecies with
pacman -S glfw
pacman -Ss glew
On raspbian
sudo apt-get install cmake
sudo apt-get install libglew-dev
sudo apt-get install libglfw3-dev
To build
mkdir build
cd build
cmake ..
#To run
pi3d ../test/tri_cube.blend
To run the nice looking test shaders (built with cmake) try,
./create -s ../shader/creation
./create -t ../test/drkwood2.png -s ../shader/tunnel
These programs will need X-Windows to run
On the raspberry, make will build pi3d ,triangle & triangle2.
These programs uses EGL2 and does not need X-Windows to run. Try it on raspberry with: ./pi3d -t test/a320_ein.pkg ./triangle2
The program ass2pkg will use assimp to read a 3d model. Each mesh will generate a meshname.mdl file and they will be packaged into a filename.pkg file containig all the meshes and images used. Only one image per mesh and the filename is used to generate a hash that is stored in the mdl file.
The Cmake version of pi3d reads all file formats supported by assimp. The Makefile version of pi3d only reads mdl and pkg files.
To illustrate with an example:
# Go to directory where model and images are stored.
cd model/tank
# To generate pkg file
../../build/ass2pkg tank.blend
# To draw pkg file with accelerated opengl
../../pi3d tank.pkg
# To draw using software-mesa version with assimp loading
# You need to fix Cmakefile to build this
../../build/gles3d vehicle-ifv-dmm08.obj
