Embodiment 1

[0052] See attached figure 1 , the present invention performs fluid animation parameter estimation and detail enhancement according to the following steps:

[0053] (1) Preliminary estimation of density field based on generative model

[0054] a. Set a random initial smoke source and velocity field, generate and collect the density field of the simulated fluid through the Euler method, and the corresponding front view and side view as training samples and generate a training data set.

[0055] b. Construct and train the conditional generation network; use the trained network to generate the density field by inputting the front view and side view sequences of the fluid animation, and obtain the preliminary density field reconstruction result.

[0056] (2) Velocity field reconstruction based on convolutional neural network

[0057] a. Collect the gas scene data generated by the Euler method as a training sample and generate a training data set, mainly including the velocity fi...

Abstract

The invention discloses a gas scene end-to-end rapid reconstruction method under a limited view, which is characterized in that the gas scene end-to-end rapid reconstruction method specifically comprises the following steps: 1) generating a preliminary estimated density field; 2) reconstructing a velocity field; 3) optimizing a density field; and 4) according to the reconstructed physical field ofthe gas scene, generating a more attractive result and a richer visual detail effect. Compared with the prior art, the method has the advantages that the gas scene is quickly and effectively reconstructed by inputting the front view and side view sequences, and detail enhancement method or artistry control is performed, so that the reconstruction performance of the smoke scene is greatly improved, and the effectiveness and robustness of the reconstruction result are ensured.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to an end-to-end rapid reconstruction method of a gas scene under a limited view by borrowing a large amount of training data and an artificial neural network. Background technique [0002] With the increasing maturity of rigid body animation simulation technology, the capture of dynamic physical phenomena has been an active research topic in the field of graphics and vision in recent decades. Due to hardware and setup constraints and reliance on complex numerical optimization and discretization operations, the capture of dynamic physical phenomena is ubiquitous and the reconstruction process often requires substantial equipment and computational costs. However, in many applications, the speed and simplicity of data capture are what people need. Real-time capture of dynamic physical phenomena can greatly promote the development of fluid simulation and play an irreplaceable...
