Dynamic Cloth Subdivision

Advanced Computer Graphics Final Project 2025

Building

To buid DynCloth, make sure that you have CMake 3.10 or newer installed.

• navigate to dynamic-cloth/build
• run cmake ../src
• run make
• MacOS
  • run ./render.app/Contents/MacOS/render --cloth ../inputs/[filename]
• Other
  • run ./render --cloth ../inputs/[filename]

Running

To begin a simulation, press a. To stop the simulation, press x. To iterate the simulation by one step, press <space>.

Cloth File

A Cloth file (extension arbitrary) defines a cloth to simulate and takes the following form:

k_structural [double, defines spring constant for structural springs]
k_shear [double, defines spring constant for shear springs]
k_bend [double, defines spring constance for bend springs]
damping [double, defines damping force to apply (simulates friction)]

correction [double, see Provot et. al. for Provot cloth correction]
subdivision angle [double, angle between vertices to subdivide]
hanging_coefficient [double, multiplied by spring force to get length of hanging]
maxiumum_subdivision [int, maximum depth of subdivisions in simulation]

m [int, number of masses in x direction] [int, number of masses in y direction]

[4 instances of corners that take the following form]
p [double, x] [double, y] [double, z]

fabric_weight [double, defines mass per node in simulation, distributed over nodes and area]

timestep [double, timestep to iterate over]
subdivision_rate [int, number of timesteps between subdivisions]

[arbitrary number of fixed points specific as the following form]
[each fixed point marks an existing point in the grid as fixed]
f [int, x value of mass] [int, y value of mass] [double, x] [double, y] [double, z]
