Rendering processing method and device and mobile terminal equipment

Abstract

The invention discloses a rendering processing method and device and mobile terminal equipment. The rendering processing method includes the following steps: enabling a vertex shader of a graphic processing unit (GPU) to acquire skeletal animation data that is pre-sampled by a central processing unit (CPU) from the texture in an offline mode; decoding pixel points in the acquired skeletal animation data into a transformation matrix to perform a vertex transformation operation; and performing GPU instantiation rendering according to the skeletal animation data subjected to the vertex transformation operation. According to the scheme provided by the invention, the smooth real-time rendering of large-scale crowds can be achieved on the mobile terminal equipment.

Description

technical field [0001] The present invention relates to the technical field of mobile Internet, in particular to a rendering processing method, device and mobile terminal equipment. Background technique [0002] In game design and virtual reality simulations, rendering of large crowds in general is a problem. On mobile terminal devices, due to the limitations of hardware computing capabilities, when the number of characters increases, the computational overhead of skeletal animation will also increase accordingly. The so-called skeletal animation, also known as joint animation, this animation generation method defines the skeleton and skin respectively. The skeleton is composed of a series of bones connected according to specific topological relationships, and the "skin" that wraps these bones is a vertex network. The position of each vertex is changed by the motion of one or more bones. In skeletal animation, the model has a skeletal structure composed of interconnected "...

Problems solved by technology

However, the CPU is also responsible for other calculations such as logic, and it is difficult to process huge animations and calculations of vertex positions in real time.

As the number of characters increases, the overhead of skeletal animation calculations and the number of Draw Calls (referring to a call to draw a graphics interface) also increase linearly, which eventually leads to the overwhelmed CPU on mobile terminal devices with relatively low performance. Handling massive crowds for real-time rendering

In addition, there are some solutions. Although GPU can be used to complete the processing of skeletal animation, most of the animation information is calculated in real time, which can be applied to computer equipment, but not suitable for mobile terminal equipment with weak computing power.

[0004] Therefore, the existing rendering processing methods still have defects in performing real-time rendering of large-scale crowds on mobile terminal devices.
