vu's Issues

Run on mobile inside flutter

https://github.com/mogol/opengl_texture_widget_example

I can run golang inside flutter easily.
Just a matter of outputting into each android and iOS buffer.

Are you interested in helping as might need some

There is a Direct3D9 wrapper here: https://github.com/gonutz/d3d9
Having a Direct3D renderer would make deployment on Windows easier, since Windows comes with DirectX drivers but usually has bad built-in OpenGL support and the average user usually is not inclined to or capable of updating their graphics drivers which often breaks something in a blue-screeny kind of way.

Doesn't compile on OpenSuse

Doesn't compile on Ubuntu (linux).

Currently the project does not compile on Ubuntu, while browsing through the code I found this:

// FUTURE
// Currently the most popular linux distro (ubuntu) is replacing the xserver
// display server with Mir. An example Mir shell can be found at:
//     http://unity.ubuntu.com/mir/demo_shell_8cpp-example.html
// Work on the linux portion will be delayed until there is an
// ubuntu version that fully supports Mir.

// The ubuntu (linux) native layer implementation.
// This wraps the linux windows API's (where the real work is done).

// // The following block is C code and cgo directvies.

You can use Qt5 to create an openGL context and this is supported under Mir.
Ubuntu on the phone fully supports Mir and I have been able to get openGL contexts working under QT5 with QML and Go.

Consistent Color/Colour naming

Hi!
awesome library thanks for the hard work so far!
I just started using it but I already fell in love :-)

But it would awesome if color would be named consistently within the library (preferably color :P).

In vu.Eng#SetColor its SetColor but in
render.Light its SetColour/GetColour().

Thx!

Importing a heightmap into VU

Hi! How would one go about importing a heightmap into VU (something like this)? I am interested in simulating some projectile collisions with terrain. Are there other options apart from adding boxes on every position to recreate the terrain mesh?
