Bonjour à tous,
Je reviens vers nous avec un nouveau mystère.
J'aimerai créer un shader qui reproduit l'effet "Glow" en HLSL :
Nom : Borderglowafter.jpg Affichages : 529 Taille : 8,5 Ko
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 :

  1. Rendu de la scene sans activer le glow
  2. Rendu de la scene avec uniquement les parties "glow"
    • Définition des parties "glow"
    • Enregistrement d'une "texture map"
  3. Blur horizontal
  4. Blur vertical
  5. 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
