Modelling of ivy geometry:
First create the basic geometry for the ivy plant. Use polygon modelling techniques to create the main stem and branches of the ivy.
Creating ivy leaves:
Model individual ivy leaves or use pre-made leaf models and distribute them along the branches. Arrange the leaves naturally.
Set up a dynamic simulation:
To simulate ivy growth using dynamic effects, use tools such as nCloth or nHair in Maya. Assign these dynamic simulations to ivy geometry to achieve realistic movement and interaction.
Creating ivy growth animations:
Procedural animation:
Use procedural animation techniques to create growth animations. Use techniques such as expressions, morphers or animated layers to gradually expand branches and make them grow over time. This method allows you to control the growth animation precisely.
Dynamic simulation:
Use dynamic simulation tools to drive growth animations. Here a combination of soft bodies and forces are used to simulate the growth of ivy. Set forces such as gravity or wind to affect the ivy geometry and make it grow naturally.
Integration of procedural and dynamic animation:
Combine procedural animation techniques with dynamic simulations to achieve more realistic and controlled growth animations. Here I have used per-programming to animate the main growth of the ivy, while using dynamic simulation to add auxiliary movements and interactions.
Optimisation and iteration:
Iterate through the animation, adjusting growth rates, branch formation, leaf distribution and any other aspects to achieve the desired look and behaviour. Preview animations and further optimise them using the playback and timeline tools in Maya.
