Gaia Sky is an open-source astronomy visualisation desktop and VR program with versions for Windows, Linux and macOS.It is created and developed by Toni Sagristà Sellés in the framework of ESA's Gaia mission to create a billion-star multi-dimensional map of our Milky Way Galaxy, in the Gaia group of the Astronomisches Rechen-Institut (ZAH, Universität Heidelberg).
Currently there is a frontend to picogen, called picogen-wx (based on wxWidgets).It is encapsulated from picogen and thus communicates with it on command-line level. . Picogen-wx provides several panels to design the different aspects of a landscape, e.g. the Sun/Sky- or the Terrain-Textur
Any of the above viewing modes allow the user to browse and load equirectangular, fisheye, or dome master images to be viewed as planet surfaces, sky images or panoramas. Images with Astronomy Visualization Metadata (AVM) can be loaded and registered to their location in the sky. Images without AVM can be shown on the sky but the user must ...
Cycloramas are often used to create the illusion of a sky onstage. By varying the equipment, intensity, color and patterns used, a lighting designer can achieve many varied looks. A cyclorama can be front lit or, if it is constructed of translucent and seamless material, backlit directly or indirectly with the addition of a white "bounce" drop.
Also, cube mapping uses the entire resolution of the texture image, compared to sphere and paraboloid mappings, which also allows it to use lower resolution images to achieve the same quality. Although handling the seams of the cube map is a problem, algorithms have been developed to handle seam behavior and result in a seamless reflection.
A diamond plate texture rendered close-up using physically based rendering principles. Microfacet abrasions cover the material, giving it a rough, realistic look even though the material is a metal. Specular highlights are high and realistically modeled at the appropriate edge of the tread using a normal map.
Bump mapping [1] is a texture mapping technique in computer graphics for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during lighting calculations. The result is an apparently bumpy surface rather than a smooth surface, although the ...
Matte painters combine their digitally matte painted textures within computer-generated 3-D environments, allowing for 3-D camera movement. [9] Lighting algorithms used to simulate lighting sources expanded in scope in 1995, when radiosity rendering was applied to film for the first time in Martin Scorsese's Casino .
