OpenGLTexture::Initialize2D

bool Initialize2D(int width, int height, int channels, const void* data, bool generateMipmap = true)

初始化一个 2D 纹理。

参数:

  • width - 纹理宽度(像素)
  • height - 纹理高度(像素)
  • channels - 通道数1=R, 2=RG, 4=RGBA
  • data - 纹理数据指针(可以为 nullptr 创建空纹理)
  • generateMipmap - 是否自动生成 mipmap默认为 true

返回: bool - 成功返回 true失败返回 false

示例:

OpenGLTexture texture;
std::vector<unsigned char> pixels(width * height * 4);
texture.Initialize2D(width, height, 4, pixels.data(), true);
