After playing around with some math, I created a 3D-software engine with JavaScript that operates on a HTML5-canvas.
This guide was really helpful:

It is a working solution with a step-by-step tutorial.
When I got stuck at some point in the matrix-multiplication, I adopted their math-library to fit my own environment and removed things I didn´t need.
Later I went to WebGL (like OpenGL for the browser).
With knowledge of how a basic software-engine works, It´s easier to understand how to work with a WebGL-canvas.
WebGL will try to use the device GPU so you can work with shaders for textures & lightning, without burning up the CPU.
Testing-room for my WebGL-script:

Textures & Lightning
Cube in 3D-space
Projection-matrix
Dedicated canvas (Lower resolution for performance gain)
Imported mesh (simple sphere in blender, exported as JSON)
Flat shading
Gouraud shading
