Journey to the Unknown by David Georg

Theme: Journey to the Unknown

In Wonderland, Alice stumbled upon a vibrant mushroom, its cap adorned with red and white spots.
Temptation led her to taste it, setting in motion a surreal transformation.
The world around her shifted, and Alice found herself fluctuating between towering heights and miniature dimensions. The mushroom, key for her fantastical journey, blurred the lines between reality and imagination, guiding her into the unknown.

Thinlense Camera

The depth of field effect produced by lenses of real cameras can be simulated in physically based rendering aswell, which gives our scene a more realistic look and draws the viewers attention to the object of interest (here our mushroom).

Shading Normals

Shading normals help us add detail to our objects, without having to 3D-model complex meshes. An additional texture containing representing surface normals can be used to simulate desired surface properties.

Alpha masking

Similar to shading normals, alpha masking helps reduce complexity when modelling objects. A seperate alpha texture tells our renderer which parts of our object are opaque, invisible or transparent. This is especially useful for adding details to our vegetation, without the need for overly complex meshes.

Open Image Denoising

Intel®'s Open Image Denoising library provides us with a way to postprocess our image by reducing the amount of noise in our picture. Surface Normal information and bsae color values of our image are used to smooth out imperfections introduced during the rendering postprocess. Especially when rendering with low samples, the image noise can be quite noticable and the denoising effect very apparent.

Area Lights

While not used here, the renderer used to create our image also has the ability to simulate area light effects. Instead of a direction or single point, we can also use areas as light sources, without having to introduce a new visible light-emitting object.
