[C++] Shader Glow DX11 - RenderTarget Texture
Bonjour à tous,
Je reviens vers nous avec un nouveau mystère.
J'aimerai créer un shader qui reproduit l'effet "Glow" en HLSL :
Pièce jointe 149794
Pour cela, j'ai parcouru le net à la recherche de tuto
GPU GEMS GLOW
Autre tuto
J'ai pu définir un algorithme simple en 5 étapes :
- Rendu de la scene sans activer le glow
- Rendu de la scene avec uniquement les parties "glow"
- Définition des parties "glow"
- Enregistrement d'une "texture map"
- Blur horizontal
- Blur vertical
- Rendu final de la scene
Je suis arrivé à la partie où je dois enregistré ma texture dans une Render Target Texture, mais je n'arrive pas à créer la Dept Stencil View.
Le résultat de la fonction me renvoie que je n'utiliser pas les bon arguements (E_INVALIDARG)...
Je me suis pourtant basé sur un exemple officiel Microsoft : http://msdn.microsoft.com/en-us/libr...(v=vs.85).aspx

Merci pour votre aide. :D
