<i style="font-size:25px;">What's new: </i>
|
||
|
|
<p style="font-size:20px;">
|
||
|
|
As before, drag on the canvas to rotate the scene, scroll on it to change focal point (perspective projection).
|
||
|
|
Double click it to pause/resume.<br>
|
||
|
|
I now added Fullscreen mode so that we can scroll on the canvas without scrolling the whole page and use single-key
|
||
|
|
hotkeys without worrying about conflicts with the editor. <br>
|
||
|
|
<a style="color:red;">Now, you can select a sphere by clicking on it (literally, click the sphere on the canvas!). And drag it around
|
||
|
|
to move it.</a><br>
|
||
|
|
When a sphere is selected, you can also scroll whe mouse wheel to change its radius, and <strong>in fullscreen mode</strong>, press B and F key to send
|
||
|
|
it backward or forward <strong>according to your view point!</strong><br>
|
||
|
|
I also optimized the code a little bit, so that the transformation matrix is completely computed in CPU,
|
||
|
|
and applied (multiplied) inside the <a href="./shader.vert">vertex shader</a>.<br>
|
||
|
|
I suggest moving spheres when pausing the scene by double clicking the canvas, otherwise the spheres are already moving.<br>
|
||
|
|
<strong>If you found the scene somehow clipped, it seems to be a bug of chromium, please simply click on 'Super Sampling' button
|
||
|
|
or refresh the page. Otherwise the interactions won't work because the coordinates are wrong.</strong>

<i style="font-size:25px;">How it works:</i><br>
|
||
|
|
I used similar method in raytracing to find the sphere it hits.<br>
|
||
|
|
The transformation methods are implemented in <a href="./lib4.header.js">lib4.header.js</a><br>
|
||
|
|
Interaction parts are in <a href="./lib4.ext.js">lib4.ext.js</a><br>
|
||
|
|
<a href="./lib4.js">lib4.js</a> most contains initialization methods for the renderer.<br>
|
||
|
|
<a href="./index.html">index.html</a> is almost pure html.<br>
