Randomized trial demonstrates improved controllability in 3D generation using sketch guidance, highlighting its practical value.

The research aims to develop a sketch-guided framework to enhance controllable text-to-3D generation.
Introduced CanvasDream for high-fidelity 3D asset creation based on text and sketches.
Developed a two-stage 3D generation framework separating geometry and appearance learning.
Utilized 3D Gaussian Splatting and a multi-view diffusion model for shape generation.
Demonstrated superior performance in 3D generation compared to state-of-the-art methods.
User studies showed enhanced controllability in produced 3D assets.

Zheng et al. (2026) studied this question.
