Soft shadow mapping #59

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Тени какие-то никакие. На ранних видео 
(когда LF использовали) были 
симпатичнее.
Нужно изучить вопрос.

Также люди просили бликов, бампа и SSAO. Было 
бы неплохо.

Нужно на GLSL, дабы не тащить ещё две 
дополнительные библиотеки - огровский 
плагин и Cg.

Огровский - это который, как я понял, 
RTShaderSystem. Как я понял, там всё на Cg.

Тени не настолько ужасны, подождут 0.8 
версии.

Текстурные тени быстрее, красивее и более 
гибкие. В частности, потому что считаются 
на видеокарте (если она умеет) и не так 
сильно зависят от количества полигонов в 
кадре.

Нужно разобраться как их использовать и 
вынести галкой в настройки видео. Это 
вопрос не только красоты теней, но и 
оптимизации.

With spotlight I get this.
Texture shadow type still casts no shadows.

Ok. I just had to mEntityGround->setCastShadows(false), because, citing OGRE 
manual:

If you're not using depth shadow mapping, OGRE divides shadow casters and 
receivers into 2 disjoint groups. Simply by turning off shadow casting on an 
object, you automatically make it a shadow receiver (although this can be 
disabled by setting the 'receive_shadows' option to 'false' in a material 
script. Similarly, if an object is set as a shadow caster, it cannot receive 
shadows.

I'll have a look at SamplesBrowser for an example shader based lighting where 
texture shadow type is working eye pleasingly.

Original comment by korn...@gmail.com on 21 May 2011 at 8:53

GoogleCodeExporter commented 9 years ago 
There's Shadows example. The desired result is as follows:
Technique: Texture
Lighting: Additive
Projection: Uniform Focused
Material: Depth Shadowmap

Here's the patch that makes use of texture shadow type instead of stencil one 
in Mahjong.

We need sonething lite this:

The example uses GLSL, so we can use something like it without additional 
dependences.

try 'max_anisotropy' in texture unit. by default it's 1. the manual says smth 
about relation to anisotropic filtering. may be when it's 1 anisotropic doesn't 
compensate enough, i.e., no visual difference between trilinear and anisotropic.

использовал шейдеры per pixel lighting для 
некоторых фишек из примеров lighthouse3d, и при 
определённых наклонах камеры получаются 
артефакты. возможно, там не предполагается 
такой поворот камеры.
