**TITLE**
[Bug] echarts-gl's 3D surface plot has an error when there is a large amount
of data, and the display is blank
**BODY**
### Version
2.0.9
### Link to Minimal Reproduction
_No response_
### Steps to Reproduce
When the amount of data reaches an order of magnitude, for example, the
x-coordinate is 0-1440 minutes in a day, the y-coordinate is 1-2000, and
1440*2000 is about less than 3 million, the 3D surface map is wrong, and a
blank is displayed. tooltips. No matter how low the impression is, there is no
problem with the amount of data below 500,000.
### Current Behavior
The 3D surface plot is wrong on the order of 500,000, and it's blank.
### Expected Behavior
A larger amount of data can be displayed, or an upper limit of the amount of
data can be given
### Environment
````markdown
- OS: WIN 10
- Browser: Chrome latest
- Framework:
````
