Programmatic hairstyle opacity compositing for 3D rendering

A system of virtual representation creation, the system comprising:

• a memory configured to store a transparency map for a virtual hairstyle;
• a personal computing device comprising graphics processing unit (GPU);
• and
• one or more network computing devices comprising processing circuitry configured to:
• identify substantially transparent pixels in the transparency map for the virtual hairstyle, wherein the virtual hairstyle includes a plurality of layers, wherein the substantially transparent pixels identify edges on hair strands within the virtual hairstyle;
• identify a first set of pixels in one or more of the plurality of layers that are a first number of pixels away from the identified substantially transparent pixels;
• increase an opacity level for a second set of pixels by a first amount, wherein the second set of pixels excludes pixels from the first set of pixels;
• generate the virtual hairstyle based on the first set of pixels and the second set of pixels having the increased opacity level, wherein the generated virtual hairstyle comprises a first version of a plurality of versions of the generated virtual hairstyle;
• wherein the GPU is configured to:
• receive a version of the generated virtual hairstyle from the plurality of versions of the generated virtual hairstyle;
• blend, via a first pass through a graphics pipeline of the GPU, one or more pixels of the received version of the generated virtual hairstyle having an opacity level greater than or equal to a threshold opacity level;
• and
• blend, via a second pass through the graphics pipeline of the GPU, one or more pixels of the received version of the generated virtual hairstyle having an opacity level less than the threshold opacity level.

A personal computing device comprising:

• a memory configured to store a version of a generated virtual hairstyle;
• and
• processing circuitry configured to:
• blend, in a via a first pass through a graphics pipeline of the processing circuitry, one or more pixels of the version of the generated virtual hairstyle having an opacity level greater than or equal to a threshold opacity level;
• and
• blend, via a second pass through the graphics pipeline of the processing circuitry, one or more pixels of the version of the generated virtual hairstyle having an opacity level less than the threshold opacity level,
• wherein the generated virtual hairstyle is generated by:
• identifying substantially transparent pixels in a transparency map for the virtual hairstyle, wherein the virtual hairstyle includes a plurality of layers, wherein the substantially transparent pixels identify edges on hair strands within the virtual hairstyle;
• identifying a first set of pixels in one or more of the plurality of layers that are a first number of pixels away from the identified substantially transparent pixels;
• and
• increasing an opacity level for a second set of pixels by a first amount, wherein the second set of pixels excludes pixels from the first set of pixels.
