![]() With a translucent sphere, you end up with slight amounts of overlapping, which you can displace the surface slightly further by an amount.Īt this point, since the R value is the same for each of the pixels, calculating this on the shader seemed like a performance warning. I tried to expand this, but realized that I could simply calculate the R and reuse it inside UE4, eliminating the need to re-simplify the formula.įor the sections below the sphere, I displaced the surface the same amount as the sphere. I simply inputted the formula into wolframalpha to leave R alone since my calculus is quite rusty (First formula under the shape on the first page).įrom there, I calculated y on the first page (Actual displacement amount, formula right under). ![]() R: Calculated radius of our imaginary spheres H: Height difference between the sphere top and the surface On the top of the 2nd page, you can see the general formula that explains the relation between: Here are the calculations that lead me to the result (Untidy as I never intended to publish this): The method I came up with for a sphere is representing the surface displacement with two spheres that are tangential to I did a series of calculations to find a mathematical approximation to how a surface would bend if a sphere (For this particular example) or a primitive shape, such as cube would be placed to a surface without stiffness. Find a teamĪfter getting the news that Tessellation will be removed from UE5, my plans of creating a soft surface plugin is gone and thus, I decided to share some of the work here for those who might need it.
