1 Float Precision

think performance

low precision in frac() to do some uv effect, after few minutes the image is slow down, uv moving not smooth.

2 RTT Screen Effect

post screen effect

3 Depth Buffer

special effect

4 MatCap

no light good performance

1、备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/

CentOS 5

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

CentOS 6

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

1编译安装msmtp，可能需要依赖库autoconf ,openssh-devel,gettext等

$ cd msmtp

$ autoreconf -i

$ ./configure; make; make install

配置文件

[root@Drupal ~]# cat /usr/local/etc/msmtprc

defaults

port 25

referred shader can be found here. with unity store free assets here.
