About
Have you ever wanted to try drawing vr graffiti? Feel what
street artists
experience when they fill the gray space with bold multicolored strokes,
ready at any moment to leave the place of unauthorized creativity.
Now you have such an opportunity. One of our clients
ordered us to develop a virtual reality application that allows you to experience the entire
graffiti creation process as realistically as possible.
Realistic Physics
Challenge
The main difficulty in developing this application was precisely the requirement
for maximum realism. In order to achieve this, it was necessary to take into
account many details that affect the naturalness and smoothness of the drawing process. In addition, there were certain difficulties with the creation of locations, since
their careful drawing required significant resources, which led to an increase in
load and reduced application performance.
Solution
The drawing process itself is calculated
mathematically using linear interpolation.
We launch a beam from a spray can of paint and aim at the texture of the wall on which
we will paint, then we calculate the pixels, and the paint is transferred to the wall.
Unity’s built-in math couldn’t cope with a lot of miscalculations, so we decided to
use the Unity C# Job System — it allows you to write simple and safe multithreaded
code that interacts with the Unity Engine to improve performance. Mesh Combiner was used to work with locations. This allowed us to reduce the load
and optimize performance.
