View-Dependent Tessellation and Simulation of Ocean Surfaces

Algorithm 1

Pseudocode of the main geometry shader.

if T.NeedsRefinement() then

 𝑡𝑒𝑠𝑠𝑒𝑙𝑙𝑎𝑡𝑖𝑜𝑛𝑇𝑦𝑝𝑒 = T.calculateRefinementType()

 T.RefineTriangle(𝑡𝑒𝑠𝑠𝑒𝑙𝑙𝑎𝑡𝑖𝑜𝑛𝑇𝑦𝑝𝑒) //Process Patterns

else if T.NeedsCoarsement() then

 T.CoarsenTriangle() //Restore original triangle and discard the rest

else

 T.Emit() //Triangle remains unaffected
