Stress Test for Copperlicht.js

Basically a test to see what is best in copperlicht. Lesson learned: WebGL can handle huge Meshes much better than a high number of clones and such. In this case I am throwing approximately 13k tris low poly trees and 100k tris grass patches at it, plus a 32k tris terrain and a cubemapped water plane. Funny enough, it renders at a decent framerate, much faster actually than in directx, where I got all trees as individual entities and the grass is only positioned around the player with a max of 2000 patches.

The highpoly trees that would fade in on a closer distance are not yet implemented. Also, still having problems in getting enough contrast in the scene, for some copperlicht specific reasons.

Cursorkeys not yet working on itch.io, I got to tweak that, but you can hit ALT-TAB to switch to an other program, then back to the browser, now keys work! (sometimes :/ and not in fullscreen)

(EDIT: this has been fixed, and just for the records, a onclick handler must be added to the canvas, calling a function:

function refocus_myself(){

var mycanvas= mycanvas=document.getElementById('3darea'); 

mycanvas.setAttribute('tabindex','0'); 

mycanvas.focus();

}

but anyway..)

)

Some problems with clumping of alpha-masked textures (pity no dds), and fog barely useable, as it adds white seams to masked textures, even when masked strictly 1 bit-ish.

However, I consider it a success, as it converts dynamically generated meshes under directx to files that overcome the vertex color "specifics" in the CC file reader (I would guess unlike most other exporters), which, frankly, was an adventure by its own. Whether that is only the case for the B3D format idk. The general idea is to add a gui to the windows version, allow settings to generate a landscape, then save it for copperlicht and potentially other engines, with a focus on fast rendering.

Update 3e notes:

This demo contains meshes exported with the latest version of fancy terrain generator for windows (3c), but has some further test features: A waterfall animation is tested. An NPC from mixamo.com is tested. A gun hand, refurbished from my CSP engine is tested. The Trees use a slightly costy yet highly beneficial method to get less clumpy due to texture masking. This is the first WebGL demo that shows the colors currently used by Fancy Terrain Generator. More details in Update Blog.
