jrMan 0.3 released! You can download it here.
New features:
- Many performance optimizations, and it is now up to twice as fast when rendering complex images!
- An improved user interface and command line options
- Doesn't require Java3D anymore
- Can generate noise() based procedural textures
This image was rendered in 52s using a 1 Ghz Duron
jrMan 0.2 released! You can download it here.
We finished implementing shadows in jrMan (using shadow maps)
This image was rendered in 11m using a 1 GHz Duron (with 8x8 samples per pixel, .25 shading rate and 64 samples for the shadow map, with more "typical" values it only takes 2m17s)
jrMan now implements high quality texture mapping (using mipmaps and trilinear interpolation) and all standard Renderman pixel filters.
This image has only 3 primitives! (2 spheres and 1 bilinear patch). All the detail is done with texture mapping and displacement mapping. It was rendered in 3m36s using a 650 Mhz Athlon.
We are doing some texture tests for jrMan 0.2.
Although it is a simple implementation of texture mapping (and is not the one which will be released with jrMan 0.2!) the results look nice.
This animation was rendered in 2h42m14s using a 650 Mhz Athlon. Each frame is 512x384 and took an average of 2m8s to render. You can click on the image to see a full size frame, or you can click here to download the entire animation (831 KB)
jrMan 0.1 released! You can download it here.
Here are some sample images rendered by jrMan 0.1:(you can see the full size images by clicking on the samples).
Added surface shader: shinymetal.
Added volume shaders: fog and depthcue
Added better error handling
New primitives added: Bilinear and Bicubic (Bezier) Patches.
Added surface shaders: constant, matte, metal, plastic, glow, randomcolors
Added light shaders: ambientlight, distantlight, pointlight, spotlight
Added displacement shader: bumptest
This scene has bezier patches, matte and metal surfaces, spot lights and a displacement shader, rendered in 3m30s using a 1 GHz Duron.
This scene has 2 spheres deformed with the bumptest displacement shader and one spot light, rendered in 1m4s using a 1 GHz Duron.
This scene has many lights and a glow surface shader, rendered in 1m49s using a 1 GHz Duron.
New primitives added: Cone, Disk, Points
Added optimization to avoid shading primitives hidden by other primitives
Added optimizations for large scenes.
This scene has 27,000 capsules and was rendered in 2m10s using a 1 GHz Duron.
This scene has over 40,0000 Spheres and was rendered in 44s using a 1 GHz Duron (fov = 80).
The same scene with 40,0000 Spheres and 10,000,000 dust particles (using Points), rendered in 22m18s using a 1 GHz Duron.
Close up (fov = 5) of the scene with 10,0000,000 dust particles, rendered in 1m21s using a 1 GHz Duron.
Close up (fov = 1) of the scene with 10,0000,000 dust particles, rendered in 1m using a 1 GHz Duron. Here can be seen the hexagons used for the Points primitive.
New primitive added: Cylinder
Also fixed a bug in the implementation of Torus
With the new optimizations in jrMan, André Descombes reports that he now rendered the one million spheres image in 7 minutes!
Note: André also tried different bucket sizes to see wich one gave best performance to render this image. This result was obtained with a 100x100 bucket size. Thank you to Giuseppe Zompatori for the idea of trying different bucket sizes!
The draft version of jrMan can now render images using two types of primitives: Sphere and Torus.
Here is a sample image rendered with jrMan by André Michel Descombes in 58 minutes using an Athlon at 1.2 GHz. This scene has 1,000,000 spheres!
