我有一个查询,它的解析函数是first_value()。
SELECT
product_id,
product_name,
list_price,
FIRST_VALUE(product_name)
OVER (ORDER BY list_price) first_product,
category_id
FROM
ot.products
WHERE
category_id = 1;
我得到的输出是:
这里我有70排。
因此,我尝试了以下新的查询:
SELECT product_id,
pro
我已经看到了很多例子,其中一些例子使用输入UIImage进行修改获得了新的UIImage。看上去:
- (UIImage *)imageByDrawingCircleOnImage:(UIImage *)image
{
// begin a graphics context of sufficient size
UIGraphicsBeginImageContext(image.size);
// draw original image into the context
[image drawAtPoint:CGPointZero];
// get
我目前正在计划一个渲染器,我有两个不同的方法,我可以处理着色。我给他们写了密码:
例A
for all models {
bind all vertex data for the model
for each shader on this model {
set shader
upload uniforms
draw indicies for this shader
}
}
例B
for all models {
collect geometry and seperate it by shader
}
sort geometry by shader in
