My version.
Using a tutorial to build an audio-reactive visualisation in Blender further enhances my skills within my Contemporary Arts practice. Visualising sound is a major interest within my work.
When following Blender tutorials, I am inspired by the limitless possibilities of 3D modelling. The limits are my technical knowledge, but with time, practice and many more tutorials, I am sure to consistently develop these skills in my artwork.
