New Raspberry Pi 4

[jomoengineer]

I was able to get the OpenGL ES 3.0 book examples to work on the RasPi 4:

First, install the mesa libs:

Code:

sudo apt-get update
sudo apt-get -y install mesa-utils

Then, download the code from Dan Ginsburg's github:

Code:

git clone https://github.com/danginsburg/opengles3-book.git

Then cd into the downloaded code

Code:

cd opengles3-book/

I found I had to set the following Environment variables to get the code to build:

Code:

set OPENGLES3_LIBRARY="/opt/vc/include/GLES3"
set EGL_LIBRARY="/opt/vc/include/EGL"

Then build the code:

Code:

cmake .
make

From here you can run one of the examples:

Code:

cd Chapter_2/Hello_Triangle/
./Hello_Triangle

Another cool item to test the Shader capability of the RasPi 4 is to down load and run ShaderToy from the following:

There are 100 shader examples that you can run through by pressing the "Esc" key.

Okay, one more.  Due to a conversation I had on another forum regarding a new BeagleBoard AI board, I went ahead and installed Quake 3 on the RasPi 4 following the instructions from the link below.  It seems to run pretty smooth on this board and I am quite impressed.
