Evermotion ParticleFlow TreeProxies. Vray Linear Workflow. Le linear workflow (LWF pour la suite) est une méthode de travail vous permettant d’eclairer vos scenes d’une manière plus naturelle.
La courbe de réponse d’un écran n’est pas linéaire Il faut donc la compenser. En d’autres termes, quand la carte graphique envoie un gris moyen à 0.5 , l’écran affiche 0.5^(1/2.2) , soit 0.21, un gris beaucoup plus sombre. Il faut donc appliquer une correction gamma pour que l’écran affiche exactement les mêmes intensitées que la valeurs numériques de la carte graphique. Du coup afin de corriger tout ça, il faut afficher les images avec un Gamma 2.2 au lieu de 1. Les courbes ci-dessous ne sont pas tout a fait juste mais le principe est la.
Avec V-ray il existe plusieurs manières de travailler avec ces paramètres. Première étape, modifier le Gamma. Mais ce n’est pas tout… il faut maintenant que vous preniez l’habitude de travailler vos maps et couleurs en « mode gamma 2.2″. Le hic c’est les textures/couleurs.
Underwater caustics effect. Michele:Nobody have an idea of how to create an animation using many texture where each one rappresent a photogram?
I suppose you want to load in many separate images from your machine and then play them back during run time to form an animation? It might be better if you use sprite sheets instead i.e. one single image that contains all the frames of the animation. Loading and using one sprite sheet is much more efficient than loading mutliple sprites during run time. Here's how you do it: Recall that to draw a sprite, you have to call spriteBatch.Draw(...) and one of the parameters is a Rectangle. I) Arrange the individual frames of the animation into a single image. Ii) Create an AnimatedSprite class that loads in the whole image as a Texture2D, and then calculate the Rectangle for each frame. Iii) During run time, grab the appropriate Rectangle from the array based on the current time.
Note that there is a limit to the size of an image file that you can load. Hope this helps! Caustics Generator. Buy The Windows versions of Caustics Generator Lite and Caustics Generator Pro are available for online purchase.
