This work presents a new technique for the real-time rendering of shadows with penumbrae based on shadow mapping. The method uses a screen-aligned texture that contains the distance between the shadow and its potential occluder. This information is u

One of the problems in virtual globes technologies is the real-time representation of vegetal species. In forest or garden representations, the low detailed plants produce a lack of realism. Efficient techniques are required to achieve accurate inter

This paper proposes a user-assisted mesh simplification method applied to CAD models converted to triangle meshes. This work offers the possibility of simplifying each subobject independently and at different levels of detail. This way, the user can

In this paper we present a new continuous multiresolution approach which has been developed for the interactive visualization of meshes in real-time applications. Our interest is to offer an efficient solution which considers submeshes, textures, nor

We propose an efficient technique for rendering visually plausible real-time soft shadows in screen space. First, we propose a novel blocker estimation technique based on a separable filter. Second, our technique performs a separable Gaussian blur in

Shadow mapping is a technique, widely used in computer graphics, for efficiently calculating shadows in real-time applications. However, shadows created with this technique can not be filtered as regular textures, causing severe aliasing. To solve th

The main problem in the real-time rendering of vegetation is the massive amount of primitives to be rendered. These primitives are needed to fully describe the geometry of the plants. However, some of them are not visible depending on the location of
